After 3 mins of my 2nd race, about 3 mins into it the motor suddenly slowed so i pulled off. Temp gun showed 134deg celcius. Cars drivetrain is really free running and the speed control (Speed Passion GT2.0 Pro) was only at 56deg. I really dont know what im doing wrong but its getting really really expensive having to buy motors all the time and quite frankly, 2 motors in such a short time im regretting ever buying speed passion products. Please help
