Stock Plasma Edge II - Sudden issue with motor
Had this Plasma Edge II for a few years and it gets used as an occasional basher, more frequently now my son is old enough to enjoy it too. We usually run it on a dusty BMX track on a 5000mah battery that gives decent runtime. The car is completely stock, with the kit included RS540 torque tuned motor.
Last time we took the car out it gave up before our Lunchbox that runs a smaller battery, and we just thought it ran out of battery first for whatever reason. This time we took it out the car ran very slowly and cut out within a few seconds. On inspection the ESC cuts out and the wires become very hot. Removing the motor the car seems to allow the car to roll relatively freely, so I don't think resistence elsewhere in the drivetrain is an issue.
Is this simply that the motor has died? Should I just replace the motor and expect to be good, or could there be something else that caused it to die? First time I've known one to exhibit this behaviour and it seems odd that it runs but very slowly, like the motor is "tight".
Cheers!
