I decided to change frame from F330 to F450 due to space for put equipment. The default PID value is not suitable for this frame. But not much change.
I also put external BEC (Castle Creation 10A). I always use this not because the speed is opto type. But it’ll make your overall system stable. ESC will not heat by BEC function.
Here the current PID. I still working on Loister PID. I also think to put GPS on above or make some plate like DJI GPS.
But current result is good. I like it :)
