step 5 transmitter adjustments
NOT ALL TRANSMITTERS HAVE THESE ADJUSTMENTS
using a receiver battery pack
If using an external receiver battery pack with the HV-Maxx ESC: 1. Plug an external 5 cell (1.2VDC/cell) receiver battery pack into the battery slot of the receiver. 2. Leave the HV-Maxxs ON/OFF switch in the OFF position, and use receiver battery packs ON/OFF switch to turn the system power on and offDo not use the ESCs switch.
12VDC BATTERY NOTE: An external receiver battery pack should be used when using the HV-Maxx with a single 12 volt battery, like a lead acid or gel cell. The ESCs built-in B.E.C. will provide limited output due to the high voltage directed through the single battery input, resulting in degraded servo and receiver performance.
For proper ESC operation, adjust transmitter as follows: A. Set HIGH ATV or EPA to maximum setting.

DISCONNECT BATTERIES WHEN NOT IN USE

Always disconnect the battery pack from the speed control when not in use to avoid short circuits and possible fire hazard. Never use fewer than 6 or more than 14 cells (7.2-16.8VDC, 1.2VDC/ cell) in the vehicles main battery pack(s). The HV-Maxx ESC is specially designed for use with sensor-based Novak HV-Series Brushless Motors Only! You may replace motor with Novak sensored motor rated up to 375W (ESCs rating)Novak SS-Series (540 size) motors will work, but will run hot and thermally shutdown. At the time of printing, there are no other motors available that work with the HV-Maxx ESCcheck our website for further updates & compatibilities. Reverse battery polarity can damage ESC & void warranty. Disconnect battery immediately if a reverse connection occurs. Heat sinks are factory-installed on your HV-Maxx ESC and MUST be used for maximum cooling and performanceNever allow separate heat sinks to touch each other or any exposed metal or conductive surface, as this will cause a short circuit & damage ESC. An external power capacitor is installed and MUST be used with your HV-Maxx ESC. Failure to use Power Capacitor will result in higher ESC operating temperatures & possible thermal shut-down. Always turn on the power of the transmitter first so that you will have control of the vehicle when you turn it on. Always insulate exposed wiring with heat shrink tubing or electrical tape to prevent short circuits, which can damage ESC. Exposure to CA glue or its fumes can cause damage to internal components of the speed control and result in premature failure. P1

7. INSTALL MOTOR IN VEHICLE
For most applications, the HV-Maxx ESC & brushless motor can be installed in the vehicle without any modification to the motor wiring. Determine the best routing for the motors sensor harness (6 small Teflon wires). [in Traxxas E-Maxx: Both the sensor harness & the ESCs input

signal harness can be routed through the gap located beneath the pinion/spur gear cover on the left side of the vehicle--between the transmission case & the battery box wall].

CONNECTION

The HV-Maxx ESC has the industry-standard receiver input connector on a user-replaceable input harness & works with all major radio brands new receivers. However, some very old receivers must have the wiring sequence in the plastic 3-pin connector housing changed. This is important, because receiver & servo electronics may be damaged if the sequence is incorrect.
1. MOTOR CAPACITORS NOT NEEDED
Novak brushless motors have built-in motor capacitors and do not require external ones on the motor (see separate Motor Sheet for more info).
2. DO NOT USE SCHOTTKY DIODES
Schottky diodes must NOT be used with reversible speed controls (including brushless). Using a Schottky diode will damage the speed control and void the products warranty.
changing wiring sequence @ receiver end
JR Hitec Futaba New KO Airtronics Z
JR, Hitec, Futaba, new KO, & Airtronics Z receivers do not need input harness re-wiring. Airtronics Z receivers have blue plastic cases & new KO cases have tabs on the input harness openings as in Figure 1.
Plug the connector on one end of the input harness into the receiver with the BLACK wire toward the outside edge of receiver case. Plug the other end of the input harness into 3-pin header inside rectangular opening on top of the HV-Maxx ESCs case with the WHITE wire toward the S (signal) marking on the ESCs label.
The HV-Maxx is very powerful, and capable of very efficient delivery of battery power to its brushless motor. Therefore, good connections must be made between the battery, speed control, and motor. A common cause of perfomance problems and ESC failures is poor connections--If you have any doubts about your soldering skill, we suggest installing the system without modifying the length of the power wires, or seeking assistance at your hobby shop or track. Once youve mounted the HV-Maxx ESC & motor, its time for the battery connections. The HV-Maxx ESC is factory-wired for two battery packs, and is equipped with high-power versions of JST/Tamiya-style battery connectors so you can use standard sport battery packs. Using different style connectors is discussed on the Motor Sheet.
3. FACTORY-INSTALLED POWER CAPACITOR why you want a power capacitor
The HV-Maxx comes with the best available Power Capacitor that drops ESC operating temperatures by 10-15F (remember, cooler means your ESC will be more efficient & faster) and dissipates noise & voltage spikes from the ESCs high switching speed.
You MUST use Novak Power Capacitors--other capacitors with similar ratings dont provide equal protection. Weve done extensive research to find capacitors with the very best quality factors.

MOUNTING THE POWER CAPACITOR: Mount the Power Capacitor to the vehicles chassis using the included double-sided tape or with tie-wraps [in Traxxas E-Maxx: You can tie-wrap the power capacitor to
the X in the middle of the rear shock tower].
Attach motor to the vehicles motor mount with included M3 motor screws (determine proper length motor screws in Step 3, #4), using one of the three sets of threaded mounting holes in the front end bell--select a mounting position that will avoid short-circuiting of motors solder tabs against conductive surfaces like aluminum or graphite. The HV motor included in the HV-Maxx brushless motor system comes with a heat sink factory-installed on it for extra cooling under excessive loads [for the Traxxas E-Maxx: The heat sink is already pre-positioned
on the motor for installation on the left hand side of the E-Maxx-install motor with the solder tabs toward the middle of the vehicle & angled slightly upward]. You can rotate the heat sink on the motor as

BATTERY PACK CONNECTIONS

The HV-Maxx system is designed to be used with two battery packs. However, it can also be used with one standard R/C battery pack (6 or 7 cells @ 1.2VDC/cell) or with one 12 volt DC battery. Using the HV-Maxx with a single battery requires special wiring and is discussed below.
If Power Cap. becomes dented or damaged, ESC failure can occur--replace immediately. Longer Power Capacitor wires decrease performance.
using dual battery packs : packs
4. CHECK MOTOR SCREW LENGTH
You must check the length of the motor screw to ensure that the motor will not be damaged. You should have no more than 1/8 of screw extending past the vehicles motor mounting plate (2-4mm). Too little can strip the threads in the end bell, and any more will cause damage & short-circuiting inside the motor & will void warranty. [the included
M3x8mm screws are the proper length for the Traxxas E-Maxx]

Old-style KO Old-style Sanwa/Airtronics
If you have an older KO or Sanwa/Airtronics, you must change the sequence of the ESCs input harness wires--Old Sanwa/Airtronics cases are black color & Old KO cases do not have tab openings, as in Figure 2 above.
Using a small flat blade screwdriver, remove the red & black wires from the plastic housing at the receiver end of the input harness as in Figure 3 below. Interchange the red and black wires in the plastic 3-pin connector housing at the receiver end of the input harness. Insert modified end of the harness into the receiver with the RED wire toward the outside edge of receiver case.

5. INSTALL PINION GEAR

refer to GEAR portion of { SET-UP sheet toSELECTION the proper MOTOR } determine gearing

FIGURE 3

With a small standard screwdriver, gently lift plastic prong until wire and metal socket easily slide out of plastic housing.
After selecting the proper final gear ratio, install pinion gear (usually about 2 teeth smaller than stock) on motor and position set-screw over the flat on the end of the motor shaft. Test fit motor in vehicle to align pinion and spur gears, then tighten pinion gear on shaft.
6. USE SPIRAL WRAP TO BUNDLE/PROTECT SENSOR WIRES
Use the spiral wrap included in the HV-Maxxs accessory kit to protect the 6 Teflon sensor harness wires between the ESC & the motor. You can also use the spiral wrap and tie-wraps to bundle the sensor harness & motor power wires neatly together. ^

needed for different applications--beware of any wires crossing the sharp ends of the heat sink, as short-circuiting may occur. Check gear mesh for proper free play. You want to have a small amount of play between the pinion & spur gears (about the thickness of a piece of paper)--check free play at several positions around the spur gear. Tighten motor into position once desired gear mesh has been adjusted-avoid using excessive force when tightening motor screws, as the threaded holes could become stripped. For vehicles that originally used 2 motors, use the included motor hole cover in place of the 2nd motor (this will help keep debris out of the slipper and the gears). Install motor hole cover using the vehicles original motor screws or with two 4-40x1/4 screws. Replace any parts of the vehicle that were removed to install the motor. [in Traxxas E-Maxx: Replace the pinion/spur gear cover]. Determine best routing for the motors power wires. If your vehicle requires unsoldering motor to route power wires through the shock tower or chassis, refer to REPLACING POWER WIRES AT ESC & MOTOR on Motor Sheet. [in Traxxas E-Maxx: Route motor power wires

along the right side of transmission--2 wires press into the wire holds on the lower side of pinion/spur gear cover, & the 3rd wire goes through the gap between the transmission case & the battery box wall].
a. Connect one battery pack (6-7 cells @ 1.2VDC/cell) to the JST/Tamiya connector at the end of the red & black wires coming from the ESCs BAT.1 solder tabs as marked on the HV-Maxx case labels. b. Connect a second battery pack to the JST/Tamiya connector coming from the ESCs BAT.2 solder tabs.

Keep receiver & antenna as far from motor, servo, battery, & power wires as possible.
Mount ESC with power wires away from other electronics & moving parts. Select a location that allows airflow through heat sinks--If the ESC gets air
flow, it will run cooler; and that means it will be more efficient, and you will go faster!
For single battery pack use, proceed to STEP 4 before completing STEPs 2 & 3 1. MOUNT HV-MAXX ESC IN VEHICLE using the included double-sided tape or with screws through the mounting ears on the sides of the case

servo plugged into ch. (#1)
To use the HV-Maxx with a single 6-14 cell (1.2VDC/cell) pack or a 12VDC battery, the pack/battery must be connected to the BAT.2 input & the BAT.1 input must be shorted together (see Fig.7 below/left). a. Cut the black wire coming from the BAT.1 () solder tab (battery wire closest to the front of ESC) about 2-3 above the solder tab. b. Strip a 1/8-1/4 of insulation off the end of the BAT.1 () black wire. Tightly twist the strands of wire & lightly tin with solder. CAUTION: When making battery wire solder connections at the HV-Maxxs Direct-Solder Wiring Tabs, it is important to not overheat & damage PCB (printed ciruit board) with the soldering iron by applying prolonged or excessive heating (PCB damage voids warranty). c. Remove the red wire from the BAT.1 (+) solder tab: Use a soldering iron to apply heat to the wires solder joint while gently pulling on the wire to remove it from the PC Boards hole. d. Solder the stripped & tinned end of the black wire coming from the ESCs BAT.1 () solder tab into the BAT.1 (+) solder tab: Insert the wire end into the BAT.1 (+) solder tab hole (if there is still solder in the hole you can melt it with the iron while pushing the wire through the hole). Apply heat to the section of wire that is sticking through the tabs hole, and add solder to the tip of the soldering iron and to the wire. Add just enough solder to form a clean & continuous joint from the plated area of the solder tab up onto the wire. Use side cutters to trim excess wire above tab (about 1/16). e. Connect battery pack (6-14 cells @ 1.2VDC/cell) to the JST/Tamiya connector at the end of the red & black wires coming from the ESCs BAT.2 solder tabs as marked on the HV-Maxx case labels.

INSTALL ESC ON/OFF SWITCH using a screw or double-sided tape where it will be easy to access [in Traxxas E-Maxx: You can screw the switch to one of the holes from the original switch]. 6. CONNECT ESC TO RECEIVERConfigure input harness wires as described in Step 1 & connect ESC to the THROTTLE CHANNEL (#2) of receiver. Be sure receiver & antenna are mounted as far from ESC, power wires, battery, and servo as possible--these components all emit RF noise when throttle is applied. On graphite or aluminum chassis vehicles, it may help
to place receiver on edge with crystal & antenna as far above chassis as possible.
Note: Mount antenna as close to receiver as possible--trail any excess wire off top of antenna mast (cutting or coiling excess antenna wire will reduce radio range).

IF USING HV-MAXX IN TRAXXAS E-MAXX DO NOT USE STOCK E-MAXX GEARING!
This WILL overheat the motor with constant thermal overloading that will result in motor system thermal shutdowns that will eventually damage the motors magnet & rotor.
This type of damage will NOT be covered under warranty!
Use the following gear ratios instead of the ones listed in the instruction manual on the HV MOTOR/WIRING SHEET. If you do not gear the E-Maxx correctly, motor damage will occur!
Batteries two 6-cell packs two 7-cell packs

Final Gear Ratio*

(no lower than)
Spur Gear Pinion Gear 12 13
24.5 : 1 (2nd gear) 28.6 : 1 (2nd gear)
*These gear ratios are based on using the stock size tires. If you are using larger than stock tires, the gear ratio MUST BE INCREASED accordingly (bigger spur gear or smaller pinion gear).
This gearing will give the E-Maxx better acceleration, better lap times at the track, and the motor will run cooler. The main concern is to avoid overloading the motor to the point the system goes into thermal shut-down. If thermal shut-down occurs, go down 1 or 2 teeth on the pinion, or go up 2 or 3 teeth on the spur. Airflow over the motor also makes a huge difference for overheating problems.
If gearing the truck up for speed runs, just dont run it to the point of thermal shut-down.
