I installed a new Power Pack A into the FT Tiny Trainer that I built from scratch in January. On my maiden flight I successfully flew without crashing six times, then on my seventh flight a turkey buzzard attacked my plane, sending it crashing to ground. Most of the damage was sustained by the swappable power module. I rebuilt the power module and the nose of the plane. After making the cosmetic repairs, I started by re-binding my NX8 Spektrum transmitter to a Spektrum AR410 receiver, and then calibrated the ESC next. Without the prop, I pushed the throttle stick from 0 to 100% and motor powered up smoothly. Then I install the prop and pushed the throttle stick from 0 to 100% and the motor started pulsing. My 3S battery is fully charged, but my ESC acts like it is sensing a low voltage condition. I changed batteries and the response is the same. If I remove the prop the motor spins up nicely. I don't have a second motor to test my ESC, so I am seeking advice on what to do next?
