....... sigh, sadly there as good as the money you are paying for it.
Did the software update, but no weird boost settings. The motor was a tried and tested 6.5
Tried it just now, the car sutterd from a standstill and was fine after that. But there was a blink indicating a hallsensor problem in the motor. Strange enough

, but tried a different motor. Same problem only worse, the car wouldn't drive from a standstill at all, and needed a push start.
Tried resetting the throttle positions, and after that the car would launch good just once. After that..........., same problem again
I can still use it sensorless but it's a really bad sensorless ESC respons wise
Tried an old GTB and everything was fine with both motors.
So if your considering getting one of these....
