Hi all, Just installed the T-motor AntiGravity motors (MN2214), and, unfortunately, only 3 out of the 4 spool up/idle properly - one of the motors stops and starts, though once I up the throttle this phenomenon stops. During the first test flight after the install, the circuit board for the motor in question began smoking (not the motor itself). I killed it as quickly as possible, but I fear I may have cooked something (hence the issue). Thoughts? Is there a place to buy replacement circuit boards for the motors?
