[FTC]: Tetrix motor controller weirdness with 4 motors

[Al Skierkiewicz]

ak,
This sounds so much like an over current issue with four motors running. When you add up the motors, the reversing as a repeatable cause and reboot to clear the problem, it seems like everything is pointing to the motor loads dragging the battery voltage down. The inductor used in the previous motors was under rated for current such that repeated stall current would eventually burn open the inductor. This does not sound like RF interference as that would produce more problems and generally be not repeatable. RF is at it's highest while the motor is running wide open or under heavy load.
