D. [. . . ] Use side cutters to trim remaining (now soldered) wire from below solder tab (about 1/16" above PCB)--make sure no wire strands have strayed to an adjacent solder tab as this can result in short-circuiting & damage to the electronics, which will void the product's warranty. ·Be sure to solder phase wires to appropriate tabs on Motor (A/B/C)· A C A = BLUE B motor B = YELLOW phase C = ORANGE wire tab I.

Be sure to position motor's Direct-Solder PCB tabs horizontally & face toward center of vehicle to avoid interference with suspension components when compressed. GEAR SELECTION (Important) HV4400 Motor @ 12 cells (14. 4VDC) With the HV4400 motor start with 2 teeth lower pinion gear than the "stock" gearing for most 1/10th scale monster trucks like the Traxxas E-Maxx & Kyosho Twin Force. Because of the broader power band of brushless motors, you can go with 1-3 tooth higher pinions than the above recommendation for more top speed, but remember that going with 3 or more teeth higher will produce excessive ESC & motor heating. Be sure to check the ESC operating temperature after making any gearing adjustments--the HV-Maxx ESC is designed to operate comfortably between 160ºF and 180ºF (warmer than typical brush-type ESC). You will want the final drive ratio in the vehicle to be: 22 : 1 9:1 12. 3 : 1 for Monster Trucks @ 12 cells for Off-Road Buggies @ 6-7 cells for Off-Road Stadium Trucks @ 6-7 cells Higher final drive ratios give longer run time at the expense of top speed. Lower ratios result in higher ESC temperatures--too low may result in thermal shut-down.

Lay end of wire flat on solder tab & use soldering iron to heat the end of the wire. IMPORTANT NOTE: DO NOT OVERHEAT SOLDER TABS Prolonged/excessive heating of solder tabs will damage PCB. CHANGING BATTERY CONNECTORS If you want to change Tamiya-style battery connectors on the ESC, we recommend using high-quality/low-resistance connectors, such as Dean's Ultra Plug. Change one connector at a time to avoid incorrect wiring (check tab I. D.

MOTOR CAPACITORS & SCHOTTKY NOT NEEDED Novak brushless motors have built-in motor capacitors, and like all reversible ESCs, do not use external Schottky diodes. CHECK MOTOR SCREW LENGTH Insert the M3 motor mounting screws that came with your vehicle through the motor mounting plate in vehicle. You need to have no more than 1/8" of screw extending past the vehicle's mounting plate (2-4mm). Too little can strip the threads in the end bell, and any more will cause shortcircuiting/damage inside the motor & will void warranty. INSTALL PINION GEAR (see GEAR SELECTION on back) Install pinion gear on motor and position set-screw over flat on end of shaft. Test fit motor in vehicle to align pinion and spur gears, then tighten pinion gear on shaft. INSTALL MOTOR IN VEHICLE · Determine the best routing for sensor harness & motor power wire. Some off-road cars may require unsoldering motor to route wires through the shock tower--refer to the "WIRING MOTOR TO ESC" section. · Using the M3 motor screws that came with your vehicle, attach motor to vehicle's motor mount using one of the three sets of threaded mounting holes--select a mounting position that will avoid short-circuiting of solder tabs on conductive surfaces such as aluminum or graphite. SENSOR HARNESS WIRING Should any of the 26G Teflon wires pull out of the connector on the motor's sensor harness, re-insert them in the appropriate slot in the connector as shown below. There is a small plastic tab that grabs a small raised barb on the back of the metal socket crimped to the Teflon wire's end. [. . . ] The included #4x1" self-tapping screws will go through the fan bracket, the ESC's mounting ears, and thread directly into the E-Maxx's stock ESC mounting holes in the chassis. MOTOR MAINTENANCE · CHECK MOTOR SCREWS Check all motor screws for loosening at regular intervals, just like other hardware on your vehicle. Note: The 3 main 4-40 socket head screws on the shaft end of the motor may become loose after a few runs of the motor and will need to be tightened. Also check the 3 flat head screws securing the end cap on the back of the motor. · CHECK MOTOR BEARING WEAR After extensive use, the ball bearings in the end bells of your brushless motor may need to be replaced.
