hello. one of my mth engines was running slower than normal and i was able to turn it up side down and give it throttle and was able to stop the motor from turning compared to the rear motor which i could not stop. any ideas? thank you

Normal. This is a KNOWN limitation of 2 motors but only one having the tachometer feedback.

Again rear motor has the tach and thus tries to maintain RPM regardless of load. The controller seeing the motor slow down would apply more power to maintain RPM.
Conversely- the front motor has no tach. It gets the same voltage the rear motor is seeing. If you load ONLY the front motor, at a low to mid throttle position, it only has the voltage or power required to spin the rear motor that is UNLOADED- sot it may be possible to load and slow the front motor significantly- maybe even stall.
Ideally unloaded, both motors should spin about the same speed- again they are given the same voltage, there is no load other than the drag of the gears and truck.
