User manual NOVAK HV MOTOR WIRING & GEAR SELECTION

[. . . ] · Cut ESC's BLACK BAT. 1(-) power wire to the desired length & strip 1/8-1/4" of insulation off the end. Solder to NEGATIVE(­) of battery #1 (6-7 cell pack). Repeat for BLACK BAT. 2(-) power wire going to NEGATIVE(­) of battery #2. · Cut RED BAT. 1(+) power wire to length & strip 1/8-1/4" of insulation off end. [. . . ] 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. VEHICLE SPUR HV4400 PINION Note: The above chart shows basic starting points for gearing vehicles with standard size tires--See our website for extended gearing information. Traxxas E-Maxx 70* 14-16 15-16 Kyosho Twin-Force 50 st st Tamiya TXT-1 40 15 st st = stock gear size = bigger than stock * · Note: Power wires can also be soldered flat on the solder tabs. Strip 3/16-1/4" of insulation off end of the new wire. Tightly twist strands of wire & tin with solder. Lay end of wire flat on solder tab & use soldering iron to heat the end of the wire. Add solder to form a clean solder joint between wire & tab. 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. Use female connectors on battery packs to avoid shorting. Change one connector at a time to avoid incorrect wiring (check tab I. D. Always use a connector that can not be connected backwards!P1 HV-Maxx double-sided taped onto radio plate BAT. 1(-) shorted to BAT. 1(+) for single battery pack operation Power Capacitor tie-wrapped to chassis ON/OFF switch screwed to hole in chassis P4 HOOK-UP INSTRUCTIONS 1. MOTOR CAPACITORS & SCHOTTKY NOT NEEDED Novak brushless motors have built-in motor capacitors, and like all reversible ESCs, do not use external Schottky diodes. Schottky diodes damage reversible ESCs & void warranty. 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. [. . . ] · Avoid using excessive force when tightening motor screws, as the threaded holes could become stripped. Motor hole cover screwed in place of 2nd motor to keep debris out of gears & slipper After extensive testing, we've found the high-power output from the HV-Maxx system to be too much for the stock E-Maxx components. We recommend the following performance upgrades: Front & Rear CVDs & CVD out drives (we used MIP CVDs & outdrives) Heavy-duty slipper w/spur gear (we used Robinson's slipper & 70T spur) Metal transmission idler gears *Check our website for more information For installation in the Traxxas E-Maxx, we recommend installing the HV-Maxx in the stock speed control mounting position with the front of the ESC facing the pinion/spur gear cover--this way the cover can still be removed without removing the speed control from the vehicle. The HV-Maxx system comes ready to install in the E-Maxx--the motor heat sink is aligned for installing the motor on the left side of the vehicle as shown here. 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. [. . . ]
