Nas Truck Rules
Motor NO Timing or Boost ALLOWED

2 cell Lipo, 21.5 Brushless motor


Lipo must be a hard cased 7.4 volt, 2s , ROAR approved Lipo (found here: http://www.roarracing.com/approvals/lipobattery.php )

When charging at the track you will need to charge in an Ammo box or lipo bag. You must run a Lipo smart stop system. This can be built into the ESC or as a separate unit.

At tech, maximum voltage for lipo is 8.44 volts and maximum temp is 110 degrees f.

Race Length = 6 minutes for heats and mains

Rear Wheel Drive Only

Ride Height - 3mm Minimum

Bodies: Any body labeled for 1/10th scale Nas Truck

Motors: Any Roar approved 21.5 brushless motor found here:

Sensor based motors only

The maximum retail price of a brushless motor shall be $129.00
Rotor Size - 12.2 mm to 12.5 mm. No Tolerances
Magnet Length - 25.0 mm +/- 1.00 mm
The inductance for each slot of the stator shall be 102.00 Micro Henries minimum and 108.00 Micro Henries maximum, measured with the rotor removed from the motor.
No hybrid (mixing of parts from approved brushless motors) allowed.

Sensor wires are to wired as follows
Pin #1- Black wire-ground potential
Pin #2- Orange wire-phase C
Pin #3- White wire-phase B
Pin #4- Green wire-phase A
Pin #5- Blue wire-temp control, 10 k Thermistor referenced to ground potential
Pin #6- Red wire-+ 5.0 volts =/- 10%
