Direct drive neu G3R

I ran an Inferno GT on road car with a Neu 1512 1900kv motor on 5S lipo and had it rigged direct drive. I was running 5S lipo. I had to be very mild with the trigger to keep the car hooked up. It did over 90 mph, but it was not at all practical. In any case, the biggest issue that I had was the lack of brakes with that "gearing" setup. I really don't have an intimate understanding of the operation of brushless motors, but I think that the gearing had something to do with the brakes, or lack thereof. Just food for thought.
