The Testing

Wet road test drive, skip to 3:24 for stupid-gearing/low-speed Mamba XL2 cogging test.

Weird thing is that the logs show peak motor RPM to be ~25k, which would translate to roughly 1100 kv @ ~100-120 A load. In the zoomed part in the third pic below, you can see the motor RPM going from 0-25k in 0.8 s; with current gearing, that 25k motor RPM corresponds to ~188 km/h wheel-speed... I know I spun the wheels a lot on the wet road, but that seems impossible. In the fourth pic below it seems like it almost takes a second for the ESC to lock commutation after throttle going through neutral. Then with smooth throttle build-up, according to the ESC, the motor revs up gradually from 0 to ~24600 RPM (with this gearing 185 km/h, 115 mph wheel-speed) in 3.3 seconds at 21.5 V, pulling 110 A. 24600 RPM / 21.5 V =1144 kv. Maybe the motor was on its way out already?
