Does anyone have real world success with this that might be able to help me out? Upgraded my Sierra this weekend to the flipsky 6.7 VESC, with 2 PTB's. I'm using the same firmware as Tawaki. I flashed the firmware, and then used the VESC tool to detect the correct FOC of the Sierra motor, then overwrote those parameters. Everything seems to be working correctly, I can shift fine and everything, but after running for a second or two the motor starts to cut out and stutter. If I run with the prop fully detuned (no thrust) it works fine. Anybody know what's going on?
