You can cycle your batteries with a commercial cycling unit*, or by leaving the system on and exercising the servos by moving the transmitter sticks until the transmitter shuts itself off. Cycling should be done every four to eight weeks, even during the winter or periods of long storage. Keep track of the batteries capacity during cycling; if there is a noticeable change, you may need to replace the batteries.

Notes: Any data in the model copied to will be written over and lost, including name, type and modulation. Upon completion, it cannot be recovered. To copy from one T10CG to another, use an optional CAMPac. (Note: The model may be flown directly off the CAMPac's memory, not requiring recopying into the 2nd transmitter.

Exponential: make the servo movement less or more sensitive around neutral for rudder, aileron, elevator, and throttle (except HELI type - use THROTTLE CURVE instead). (ACRO typethrottle EXP and THROTTLE CURVE can not be activated simultaneously). Why use expo? Many models require a large amount of travel to perform their best tricks. However, without exponential, by setting different exponentials for each rate, you can make the effectiveness of small corrections similar in each rate, as in our example below. The best way to understand exponential is to try it: Having made no changes yet in the D/R,EXP screen, move SWITCH D to down (toward the AILERON STICK). Cursor down to EXP and dial to +100%.

Special note for helicopters: Helicopter model types have just a single rate for each switch position rather than a rate for each side of the servos travel per switch position. Additionally, setting the D/R,EXP for each switch position requires cursoring back to the No. setting, allowing dual rates to be assigned with idle-up and other features on certain switches, and does not require putting
Special note for conditions: The helicopter and glider programming offers you the choice of Cond. This option allows you to have a separate rate for each of the 3 controls automatically selected when changing conditions, for a total of FIVE rates available. Simply change the switch choice to Cond. and then: (HELI) press the CURSOR LEVER to toggle through the 5 conditions while setting the rates. (GLID) activate the corresponding condition to edit the rates. GOAL of EXAMPLE: STEPS: Set up dual rates and exponential in a Open D/R,EXP. HELI model. Choose channel.

Note: Every aircraft snaps differently due to its C.G., control throws, moments, etc. Some models snap without aileron; others snap on elevator alone. Most models snap most precisely with a combination of all 3 surfaces. Additionally, rate of speed and acceleration when using the snap switch will affect how the model snaps. For information on using gyros with airplanes for cleaner precision maneuvers, such as snaps and spins without over rotation, see p. 74. Adjustability: Travel: Adjust the amount of elevator, aileron and rudder travel automatically applied. Range: -120 to +120 on all 3 channels. Default is 100% of range of all 3 channels. Directions: Note: for simplicity, the radio refers to snaps that use UP or positive elevator as U or UP snaps. This is more commonly referred to as a positive or inside snap. D or DOWN snaps are more commonly referred to as negative or outside snaps. R/U = Right positive R/D = Right negative L/U = Left positive L/D = Left negative snap roll Assignment of the 2 switches (DIR-SW1/2) to change snap directions is fully adjustable and optional. If you wish to have only one snap, leave the switches as NULL. (If assigned, SW1 SW2 Caution: it is critical that you remember if you assigned switches to select the three additional snaps. For example, assign SWITCH A SWITCH A for elevator dual rates. SWITCH A DOWN) you pull your snap SWITCH. The model will: use the throws set in the snap programming (the low rate elevator has no effect); and Both of these may come as a great surprise and risk crashing if you are unprepared. Safety Switch (SAFE-MOD): a safety may be set up on your landing gear SWITCH, preventing accidental snap rolls while the landing gear is down. The safety switch is turned on and off with the landing gear SWITCH. ON: the safety mechanism is activated when the landing gear SWITCH is in the same position when this feature is changed to ON. Snap rolls will not be commanded even if the snap roll SWITCH is turned on with the gear SWITCH in this position. When the landing gear SWITCH is moved to the opposite position, snap rolls may be commanded. OFF: activates the safety mechanism in the opposite position from the ON function. FREE: the safety mechanism is completely turned off. Snaps can be commanded regardless of the gear SWITCH POSITION. Note: The location of the safety switch always follows channel 5. If channel 5 is reassigned to switch C, for example, switch C is now the safety. If channel 5 is nulled or used as the second aileron servo, the safety function will not be available.

Throttle delay function THR-DELAY (ACRO): The THR-DELAY function is used to slow the response of the throttle servo to simulate the slow response of a turbine engine. A 40% delay setting corresponds to about a one-second delay, while a 100% delay takes about eight seconds to respond. For helicopters, see DELAYS, p. 103.
This function may also be used to create a slowed servo on a channel other than throttle. This is accomplished by plugging the desired servo (Ex: gear doors) into CH3 (THR), throttle into an auxiliary channel such as 8, and then using

BUTTERFLY (crow) mixing (GLID):
BUTTERFLY (often called "crow"- see GLID and is usually used to make steep descents or to limit increases in airspeed in dives. Two separate BUTTERFLY settings are available. (CIR1 CIR2) Adjustability: Activation: Proportional by moving the THROTTLE STICK. Switch: Mix SWITCH is selectable. A to H: SWITCH A to H NULL: always on. Also LOGIC SW (Lsw1 to 3) may be assigned. Set up LOGIC SW: See p. 38. Inversely proportional to THROTTLE STICK: provides a proportional increase in amount of airbrake action as THROTTLE STICK is lowered (when SWITCH A (assignable) is in the down position). Includes selectable stick position where airbrake begins. If you would like to have the airbrake be directly proportional to throttle stick, you will need to reverse the THR-REV function. Note that this changes the throttle stick direction for all models. See page 38 for instructions. Elevator settings: (adjustable in the B.FLY-ELE) B.FLY-ELE links elevator with the BUTTERFLY function. Elevator rate is adjustable in a 3 point curve. Point 1: PRESET point. (Fixed) Point 2: MID point. Position and rate are adjustable. Point 3: END point. Position and rate are adjustable. Delayed reaction: You can suppress sudden changes in your model's attitude when BUTTERFLY is activated by setting the delay (DELAY point together. A setting of 100% slows the servo to take approximately one second to travel the prescribed distance. Channels controlled: BUTTERFLY, including setting to 0 to have no effect. Twin aileron servos: If AIL-DIFF function is inhibited, then AIL1 and AIL2 settings will have no effect. If AIL-DIFF is active, then CH1 and CH7 may be independently adjusted. Normally both ailerons are raised equally in BUTTERFLY, and the elevator motion is set to maintain trim when the ailerons rise. Different amounts may be set for each aileron to correct for torque reactions and other unique characteristics of the model. Be sure you understand what dropping ailerons will do when in BUTTERFLY. Along with creating an enormous amount of drag (desireble for spot landings), this also creates "wash-in", a higher angle of attack where the ailerons are, and encourages tip stalling. If you are using this for aerobatic performance and not "sudden stops", consider raising the

OFFSET: Optional separate trims in addition to those for the normal condition. This function is used to automatically change helicopter tends to drift to the right at high speed, so an aileron offset may be applied to offset the helicopter to the left. The necessary elevator offset varies with model geometry, so it must be determined by noting collective pitch changes at high speed. The rudder offset is affected by both revo. mixing and trim lever movement while in the offset function. Adjustability: Complete switch assignability, plus a CONDITION SELECT switches between individual trims for each of the idle-ups. When OFFSET is active (its switch is on), moving the TRIM LEVERS adjusts the stored offset, not the trims in the normal condition. When OFFSET is inactive (its switch is off), the OFFSET and any trim adjustments condition.) When OFFSET Rapid jumps caused by large offsets can be slowed using the DELAY function.

Receiver What is a governor? A governor is made up of a set of sensors which read the RPM of the helicopters head, and a control unit that automatically adjusts the throttle setting to maintain a constant head speed regardless of changes in pitch of blades, weather conditions, etc. Governors are extremely popular in competition helicopters due to the consistency provided.
How does it help in helicopter setup? The governor eliminates the need to spend large amounts of time setting up throttle curves, as it automatically adjusts the engines RPM to maintain the desired head speed. GOVERNOR: The Governor mixing function is used to adjust the GV-1 (Governor) speed settings (rS1, rS2, rS3) from the transmitter. (If you are using a different governor, follow the manufacturer's instructions.)

The GV-1 controls throttle when it is active, so the throttle will not obey any FailSafe setting presets for throttle in the and the throttle obeys the FailSafe throttle commands. Expert Tip: Mounting the GV-1 to the counter gear instead of the fan

Never blow into a part (wheel pant, cowl) to remove berglass dust, as the dust will blow back into your eyes. Always wear safety goggles, a particle mask and rubber gloves when grinding, drilling and sanding berglass parts. Vacuum the parts and the work area thoroughly after working with berglass parts. We, as the kit manufacturer, provide you with a top quality, thoroughly tested kit and instructions, but ultimately the quality and yability of your nished model depends on how you build it; therefore, we cannot in any way guarantee the performance of your completed model, and no representations are expressed or implied as to the performance or safety of your completed model. Remember: Take your time and follow the instructions to end up with a well-built model that is straight and true.

IMPORTANT BUILDING NOTES

There are three types of screws used in this kit: Sheet Metal Screws are designated by a number and a length. For example #6 3/4" [19mm]. This is a number six screw that is 3/4" [19mm] long. Machine Screws are designated by a number, threads per inch, and a length. For example 4-40 3/4" [19mm]. This is a number four screw that is 3/4" [19mm] long with forty threads per inch. Socket Head Cap Screws (SHCS) are designated by a number, threads per inch, and a length. For example 4-40 3/4" [19mm]. This is a 4-40 SHCS that is 3/4" [19mm] long with forty threads per inch When you see the term test t in the instructions, it means that you should rst position the part on the assembly without using any glue, then slightly modify or custom t the part as necessary for the best t. Whenever the term glue is written you should rely upon your experience to decide what type of glue to use. When a specic type of adhesive works best for that step, the instructions will make a recommendation. Whenever just epoxy is specied you may use either 30-minute (or 45-minute) epoxy or 6-minute epoxy. When 30-minute epoxy is specied it is highly recommended that you use only 30-minute (or 45-minute) epoxy, because you will need the working time and/or the additional strength. Photos and sketches are placed before the step they refer to. Frequently you can study photos in following steps to get another view of the same parts.
The Yak-55M is factory-covered with Top Flite MonoKote KIT INSPECTION lm. Should repairs ever be required, MonoKote can be patched with additional MonoKote purchased separately. MonoKote is packaged in six-foot rolls, but some hobby Before starting to build, take an inventory of this kit to make shops also sell it by the foot. If only a small piece of MonoKote sure it is complete, and inspect the parts to make sure they is needed for a minor patch, perhaps a fellow modeler are of acceptable quality. If any parts are missing or are not would give you some. MonoKote is applied with a model of acceptable quality, or if you need assistance with assembly, airplane covering iron, but in an emergency a regular iron contact Product Support.

7. Locate all of the components shown in the picture, a 4-40 x 5 3/4" [146mm] pushrod wire and an additional 4-40 nut. Examine the diagram that shows the proper way to assemble the swivel ball link. Mount the swivel ball link into the hole you drilled in the servo arm.
This is what a properly soldered clevis looks like shiny solder with good flow, no blobs and flux removed.
8. The photo shows how your pushrod assembly should
look. Center the aileron and the aileron servo. Install the servo arm onto the servo and the solder clevis into the second most outer hole of the control horn. Mark where to cut the pushrod wire. Cut the wire on the mark you made. Remove all of the components of the pushrod wire from the clevises and the control horn. Solder the pushrod wire to the solder clevis using the soldering Hot Tip that follows.
9. After the solder cools, install the pushrod assembly
to the aileron servo and the aileron. Be sure to use thread locker on the nuts and a silicone clevis keeper on the clevis.
1. Slide the landing gear into the fuselage on both the left
and right side of the fuselage. The straight side of the landing gear should be towards the front of the fuselage.
10. Glue a 5/16" x 1" [7.9mm x 25mm] wood dowel into
the two outermost holes in the wing root. The dowel should extend out of the wing 1/2" [13mm].
11. Repeat steps 1- 10 for the left wing panel.
ASSEMBLE THE FUSELAGE Install the Main Landing Gear

Be sure to apply thread locker to the screw threads. work with when the landing gear is installed.
Install the Stabs & Elevators
1. Including the servo lead from the servo, you will need
58" [1475mm] of wire to reach from the elevator to the radio compartment in the airplane. For a Futaba servo this means you will need some combination of servo leads to equal 45" [1145mm] or more. We used a 12" [305mm] and 36" [914mm] lead plugged together. Be sure to secure all of the connections with heat shrink tubing, tape or some other method to secure all of the connections. If you have the ability make your own leads you may choose to do this and eliminate one of the connections. Make two of these extensions. Install the rubber servo pads and metal grommets on the servos.

you will need to use a 1-1/2" heavy duty servo arm. We used the Futaba aluminum arm (FUTM2118). Enlarge the hole that is 1-1/4" [32mm] from the center of the servo spline with a 1/8" [3.2mm] drill. (The 1-1/4" [32mm] dimension is approximate. You may nd that for your brand of servo, the holes might be spaced slightly different than the Futaba. Open up the hole closest to this dimension.)
2. To achieve proper elevator control
6. Guide the servo lead through the stab exiting through
the root rib. Secure the servo cover in place with four #2 x 3/8" [9.5mm] screws and #2 at washers.
3. Center your servo and then install the arm to the servo.
Remove the servo tray cover from the left stab. Place the servo on the tray with the servo arm centered in the slot. Glue a 5/16" x 9/16" x 13/16" [8mm x 14mm x 21mm] wood servo block on each side of the servo.

plate in the elevator servo. Position the large nylon black control horn on the plate, in line with the pushrod wire. Position the control horn on the hinge line the same way you did for the ailerons. Drill a 3/32" [2.4mm] hole through each of the holes in the control horn. Drill only through the plywood plate. Do not drill through the top of the control surface. Mount the horn with four #4 x 1/2" [13mm] screws. length tube into the forward most hole in the rear of the fuselage and the longest tube in the rear hole in the fuse. Through the opening in the back of the fuselage, install the servo leads into the fuselage up to the radio compartment and then test t the stabs to the fuselage.

you are satised with the t, glue the stabs one side at a time to the fuselage with 30-minute epoxy. Apply the glue to the tubes, the root rib of the stab and the fuselage side. Clean any excess epoxy with a paper towel and rubbing alcohol. Use masking tape to hold the stabs 11. Repeat steps 2-10 for the right side stabilizer / elevator. tight to the fuselage while the glue is curing. 10. Install the servo pushrod as shown. Make any adjustments required to the arm to get the proper length for the pushrod so when the servo is centered, the elevator is aligned with the stabilizer.

To achieve can add the second servo later. this alignment, the hinges will be fairly deep in the n. Also note that the hinges must be perpendicular to the leading edge.
2. Again without glue, test t the rudder to the n. Remove the rudder and all the hinges. Add a small drop of oil to the pivot point on the hinges. This will prevent the epoxy from adhering to the pivot point. Make sure oil does not get on the gluing surface of the hinge. If it does, clean the oil off with a paper towel square dampened with denatured alcohol. 3. Mix up approximately 1/4 oz. [7.4cc] of 30-minute epoxy.
Use a toothpick to thoroughly apply the epoxy in the holes in the n and rudder. Use the toothpick to get the epoxy out of the opening of the holes in the rudder and n so it doesnt get into the hinge pin. Wipe away any excess epoxy around the outside of the holes with a couple of the small paper towel squares dampened with denatured alcohol. hinges that go into the n. Insert each hinge into the n and wipe away any excess epoxy that squeezes out of the hole.
4. Use the toothpick to apply epoxy to the ends of the rudder 1. Modify two large black nylon control horns as shown. This is easily completed with a high speed motor tool, small belt sander or a sanding block with coarse sandpaper. As you did with the ailerons horns, locate the plywood plate on each side of the rudder. Position the horns over the plates. Drill a 3/32" [2.4mm] hole through each of the holes in the control horn. Drill only through the plywood plate. Do not drill through the control surface. Mount the horn with four #4 x 1/2" [13mm] screws. Do this on both sides of the rudder.
SINGLE SERVO INSTALLATION If you will be installing two servos, skip ahead to, Two Servo Installation. servo arm installation you will need one of the aluminum servo arms included in the kit and one of the round servo disks included with your radio system. The round servo disk needs to be at least 1" [25mm] in diameter.

5. Locate four heavy duty screw lock connectors, metal
6. Use wire cutters to cut the supplied braided cable into
3. Install your servos into the rudder servo tray using
the hardware that came with your servo. Center the servos and then install the servo arm.
4. Locate two 4-40 x 5-3/4" [146mm] thread pushrod wires.
Cut off the threaded end of the wire leaving an unthreaded wire 3-1/2" [89mm] in length.
7. Wrap the cable back around and through the swage.
8. Use pliers to pull the cable from the rst loop to reduce
the size of the second loop. Squeeze the swage with pliers and then cut off the excess wire. Do this for both wires.
2. Adjust the tension of the wires by turning the clevises in
or out on the connector. Then, lock the nut against the clevis. Be sure to apply a drop of thread locker to the nut.

Install the Engine

The following instructions cover the installation of the DLE55. Other engines will require similar installation. You will need to determine the proper mounting hole positions and location for the throttle connections for your choice of engine. MOUNT THE ENGINE AND INSTALL THE THROTTLE AND CHOKE SERVOS The following instructions will show how to install a servo activated choke. We know some modelers may wish to use some sort of a manual linkage. It is recommended that you read the installation instructions and then decide which method you prefer. We will not be showing installation of a manual linkage. Most modelers will nd that this is easy to do and requires little explanation.
9. Install a 4-40 thread clevis, 4-40 nut and a silicone
clevis keeper onto the threaded connectors.
10. Inside of the fuselage are two white plastic guide
tubes. Slide a wire into each of the tubes until they exit out the fuselage sides. Connect the clevis to the hole in the aluminum servo arm. Note: When you connect the clevises to the arm, be sure that the wires cross each other. In other words, the wire attached to the right side of the servo arm exits the left side of the fuselage and the left side clevis exits out the right side of the fuselage.

side of the fuselage. Be sure to leave at least 8" between the radio switch and any of the components of the engine and the ignition system, including the ignition switch.
5. Make all of the servo connections with the receiver. Secure the battery connection to the switch lead with tape, heat shrink tubing or some other method for securing the wires.
3. If you will be installing a pilot, install it securely in the

cockpit.

4. Attach the canopy hatch to the top of the fuselage with
four 4-40 x 3/4" [19mm] screws, #4 lock washers and #4 at washers. Test t the canopy to the top of the fuselage to determine the mounting position.
5. Determine the position of the canopy and make a couple
of reference marks on the fuselage so that you can easily locate the canopy position. Remove the canopy and apply a bead of RC 56 glue to the inside of the canopy. Note that the canopy rests on both the canopy hatch and the fuselage. You only want the glue to be applied to the canopy where it will be in contact with the canopy hatch. Tape the canopy to the canopy hatch. Be sure the tape is only applied to the hatch and not the fuselage below the hatch. and remove the hatch from the fuselage being careful not to disturb the canopy.
6. Remove the screws holding the canopy hatch in place 7. Clean any excess glue that may have gotten on the 8. Remove the canopy hatch from the fuselage. Mix a small
fuselage or the back portion of the canopy with a damp cloth. When you have removed the excess glue, reinstall the canopy onto the fuselage. IMPORTANT! Be sure that you reinstall all four of the screws that secure the canopy hatch. The hatch must be tight to the fuselage while the glue dries. If needed, add additional tape to secure the canopy. Allow the glue to dry at least 12 hours.

APPLY THE DECALS

1. Use scissors or a sharp hobby knife to cut the decals

from the sheet.

2. Be certain the model is clean and free from oily ngerprints
and dust. Prepare a dishpan or small bucket with a mixture of liquid dish soap and warm waterabout one teaspoon of soap per gallon of water. Submerse the decal in the soap and water and peel off the paper backing. Note: Even though the decals have a sticky-back and are not the water transfer type, submersing them in soap & water allows accurate positioning and reduces air bubbles underneath. decal down, use a paper towel to wipe most of the water away.

3. Position decal on the model where desired. Holding the 4. Use a piece of soft balsa or something similar to squeegee
remaining water from under the decal. Apply the rest of the decals the same way.
GET THE MODEL READY TO FLY Check the Control Directions
1. Turn on the transmitter and receiver and center the trims.
If necessary, remove the servo arms from the servos and reposition them so they are centered. Reinstall the screws that hold on the servo arms.

2. With the transmitter and receiver still on, check all the
control surfaces to see if they are centered. If necessary, adjust the clevises on the pushrods to center the control surfaces. 4-CHANNEL RADIO SETUP (STANDARD MODE 2) RUDDER MOVES RIGHT RIGHT AILERON MOVES UP LEFT AILERON MOVES DOWN
When connecting pushrods and setting up your control throws, it is critically important to use proper pushrod geometry that is the distance from the pushrod on the servo arm to the center of the output shaft (servo arm offset) compared to the distance from the pushrod on the control horn to the pivot point (control horn offset). EXTREMELY DANGEROUS PUSHROD HOOKUP
Pushrod far out on the servo arm

3. Make certain that the control surfaces and the carburetor
respond in the correct direction as shown in the diagram. If any of the controls respond in the wrong direction, use the servo reversing in the transmitter to reverse the servos connected to those controls. Be certain the control surfaces have remained centered. Adjust if necessary.
One particularly dangerous situation arises when the pushrod on the servo arm is too far out and the pushrod on the control horn is too close in. This setup is usually chosen by pilots who are trying to achieve maximum, monster control throws for 3D ight. But with your pushrods set up this way, any free play (slop) in the linkages or servo will be greatly magnied, possibly causing destructive control surface utter. Additionally, if you have to turn your ATVs way down for normal throw, the result will be poor resolution and poor servo holding/ centering capabilities. More importantly, too much force may be transmitted back to the servo, possibly causing control surface blowback, stripped servo gears or stripped servo armsthe latter two likely causing a crash. PREFERRED PUSHROD HOOKUP

Set the Control Throws

To ensure a successful rst ight, set up your Yak-55M according to the control throws specied in this manual. The throws have been determined through actual ight testing and accurate record-keeping, allowing the model to perform in the manner in which it was intended. If, after you have become accustomed to the way the Yak-55M ies, you would like to change the throws to suit your taste, that is ne. However, too much control throw could make the model too responsive and difcult to control, so remember, more is not always better.

Closest in on servo arm Farthest out on control horn
Here is an optimum pushrod setupthe pushrod is close in on the servo arm and far out on the control horn. This situation gives the greatest mechanical advantage of the servo over the control surface, which will increase the servos centering capabilities and output torque, minimize any free play in the system and allow high ATV settings for optimum servo resolution and positive control feel. Note: When the pushrod is close in on the servo arm, make certain the servo arm can travel through its full range of movement without the pushrod (or clevis or other type of connector) interfering with the servo arm, output shaft or servo case.
ACCEPTABLE PUSHROD HOOKUP

Balance the Model (C.G.)

More than any other factor, the C.G. (center of gravity/ balance point) can have the greatest effect on how a model ies and could determine whether or not your rst ight will be successful. If you value your model and wish to enjoy it for many ights, DO NOT OVERLOOK THIS IMPORTANT PROCEDURE. A model that is not properly balanced may be unstable and possibly unyable.
Move the pushrod farther out on the servo arm
But leave the pushrod in the farthest out location on the control horn.
If the optimum situation doesnt provide enough control throw, the pushrod may be moved inward on the control horn, but its better to go farther out on the servo arm because this will At this stage the model should be in ready-to-y condition with introduce less free play than the alternative. Only after moving all of the components in place including the complete radio the pushrod all the way out on the servo arm, if you still cant get system, engine, mufer, propeller, spinner and pilot.

Note: If you have a computer radio, it is always desirable to set your ATVs to 100% (or as 1. Use a ne-point felt tip pen to mark lines on the top of near 100% as possible to achieve the control throw required). wing on both sides of the fuselage 6.5" [165mm] back from If setting up a model that requires extraordinary control surface the leading edge. Apply narrow (1/16" [2mm]) strips of tape throw (for 3D ying for example), start by maxing-out your over the lines so you will be able to feel them when lifting the ATVs (typically 130% -- 140%). Then, the dual rates in your model with your ngers. normal ight mode will still be acceptably high (70% -- 80%) This is where your model should balance for the rst for good servo resolution. ights.

Moving the C.G. forward will improve the above, adjust the location of the pushrod on the servo arm or on smoothness and stability, but the model will then be less the elevator horn and program the ATVs in your transmitter to aerobatic (which may be ne for less-experienced pilots). increase or decrease the throw according to the measurements Moving the C.G. aft makes the model more maneuverable in the control throws chart. and aerobatic for experienced pilots.

Measure and set the low rate elevator throws and the the recommended balance point and do not at any time high and low rate throws for the rest of the control surfaces balance the model outside the specied range. the same way. NOTE: The throws are measured at the widest part of the elevators, rudder and ailerons.

2. With the wing attached to the fuselage, all parts of the
model installed (ready to y) and an empty fuel tank, place the model upside-down and lift it upside-down at the balance point you marked.

3. If the tail drops, the model is tail heavy. If possible, move
the battery pack and/or receiver forward to get the model to balance. If the nose drops, the model is nose heavy. If possible, move the battery pack and/or receiver aft. If needed, use Great Planes stick-on lead (GPMQ4485). To nd out how much weight is required, place incrementally increasing amounts of weight on the fuselage over the location where it would be mounted inside until the model balances. A good place to add stick-on nose weight is to the rewall. Do not attach weight to the cowlthis will cause the mounting screws to open up the holes in the cowl. Once you have determined the amount of weight required, it can be permanently attached. If required, tail weight may be added by cutting open the bottom of the fuse and gluing it permanently inside. Note: If mounting weight where it may be exposed to fuel or exhaust, do not rely upon the adhesive on the back to permanently hold it in place. Over time, fuel and exhaust residue may soften the adhesive and cause the weight to fall off. Instead, permanently attach the weight with glue or screws.
4. IMPORTANT: If you found it necessary to add any weight,
recheck the C.G. after the weight has been installed.
Balance the Model Laterally
1. With the wing level, have an assistant help you lift the
model by the engine propeller shaft and the bottom of the fuse under the TE of the n. Do this several times.

AMA SAFETY CODE EXCERPTS

Read and abide by the following excerpts from the Academy of Model Aeronautics Safety Code. For the complete Safety Code refer to Model Aviation magazine, the AMA web site or the Code that came with your AMA license.

General

1) I will not y my model aircraft in sanctioned events, air shows, or model ying demonstrations until it has been proven to be airworthy by having been previously, successfully ight tested. 2) I will not y my model aircraft higher than approximately 400 feet within 3 miles of an airport without notifying the airport operator. I will give right-of-way and avoid ying in the proximity of full-scale aircraft. Where necessary, an observer shall be utilized to supervise ying to avoid having models y in the proximity of full-scale aircraft. 3) Where established, I will abide by the safety rules for the ying site I use, and I will not willfully and deliberately y my models in a careless, reckless and/or dangerous manner. 5) I will not y my model unless it is identied with my name and address or AMA number, on or in the model. Note: This does not apply to models while being own indoors. 7) I will not operate models with pyrotechnics (any device that explodes, burns, or propels a projectile of any kind).
1. Fuelproof all areas exposed to fuel or exhaust residue
such as the cowl ring, cowl mounting blocks, wing saddle area, etc. in the manual.
2. Check the C.G. according to the measurements provided 3. Be certain the battery and receiver are securely mounted
in the fuse. Simply stufng them into place with foam rubber is not sufcient.
4. Extend your receiver antenna and make sure it has a
strain relief inside the fuselage to keep tension off the solder joint inside the receiver. 5. Balance your model laterally as explained in the instructions.
6. Use threadlocking compound to secure critical fasteners
such as the set screws that hold the wheel axles to the struts, screws that hold the carburetor arm (if applicable), screw-lock pushrod connectors, etc.

Radio Control

1) I will have completed a successful radio equipment ground check before the rst ight of a new or repaired model. 2) I will not y my model aircraft in the presence of spectators until I become a qualified flier, unless assisted by an experienced helper.
7. Add a drop of oil to the axles so the wheels will turn freely. 8. Make sure all hinges are securely glued in place. 9. Reinforce holes for wood screws with thin CA where
appropriate (servo mounting screws, cowl mounting screws, etc.). and the throws are set up according to the manual.
10. Conrm that all controls operate in the correct direction 11. Make sure there are silicone retainers on all the clevises

your glide path and airspeed. If you are going to overshoot, smoothly advance the throttle (always ready on the right rudder to counteract torque) and climb out to make another attempt. When youre ready to make your landing are and the model is a foot or so off the deck, smoothly increase up elevator until it gently touches down. Once the model is on the runway and has lost ying speed, hold up elevator to place the tail on the ground, regaining tail wheel control. One nal note about ying your model. Have a goal or ight plan in mind for every ight. This can be learning a new maneuver(s), improving a maneuver(s) you already know, or learning how the model behaves in certain conditions (such as on high or low rates). This is not necessarily to improve your skills (though it is never a bad idea!), but more importantly so you do not surprise yourself by impulsively attempting a maneuver and suddenly nding that youve run out of time, altitude or airspeed. Every maneuver should be deliberate, not impulsive. For example, if youre going to do a loop, check your altitude, mind the wind direction (anticipating rudder corrections that will be required to maintain heading), remember to throttle back at the top, and make certain you are on the desired rates (high/low rates). A ight plan greatly reduces the chances of crashing your model just because of poor planning and impulsive moves. Remember to think.

Landing

To initiate a landing approach, lower the throttle while on the downwind leg. Allow the nose of the model to pitch downward to gradually bleed off altitude. Continue to lose altitude, but maintain airspeed by keeping the nose down as you turn onto the crosswind leg. Make your nal turn toward the runway (into the wind) keeping the nose down to maintain airspeed and control. Level the attitude when the model reaches the runway threshold, modulating the throttle as necessary to maintain
Have a ball! But always stay in control and y in a safe manner.
Good Luck And Great Flying!
