Trying out my OpenRC F1 car. It has a 21 turn brushed motor and a 6-cell Ni-MH pack. Way too hot. I'm going to try an 80 turn motor soon. I could only give about 25% throttle before it would go nuts, and I measured a 37,3 km/h speed on my fastest run, at very low throttle and super careful acceleration.
Then I tried my Monster truck, but it was boring on asphalt so I gave up and went home.
