Burnt MOSFETs, Desync, BEC & Power Board Faults — Repaired or Replaced
(469) 457-0134When one motor cuts out, spins up on its own, or the aircraft drops out of the sky, the electronic speed controllers and power distribution are usually to blame. We test each ESC and the power board together, because a failed ESC rarely fails alone.
Every ESC bench-tested for MOSFET shorts, desync and throttle response.
Blown FETs and drivers replaced at component level.
5V and 12V rail faults repaired so the camera and controller stay alive.
PDB traces, pads and connectors rebuilt after a short or crash.
Windings, bell bearings and connectors inspected while the frame is open.
Spin-up balance and thermal check on the bench before return.
Each unit measured for shorts and throttle tracking.
Power board, wiring and motors checked, not just the dead ESC.
Components reworked or matched ESCs swapped as a set.
Motors spun under load and temperatures recorded.
