The Novak BL in the T1R is a quick combo, I have found like other motors, play around with the gearing to get the best for each track (personally think the motor performs more like a 12t)
The best part is not having to work on the motor.
The worst part is when you hit reverse and back the car into your bare foot at 100 mph (OUCH shouldn't play with that)
word of warning
don't try to reset the speed control if it is driving the motor,
hold the radio trigger in the neutral position for the speedo before you hit the button.(no motor drive)
Later versions have protection to stop a blow up occuring
