Yeah i know there is that "joker"-setting but i don't want to try it first with expensive castles
I'll try it maybe with cheap esc:s first to see what that setting does. I changed TC your flashed HK:s and all working fine with standard settings. I hope someone explains when find out what that other esc setting does, there's nothing in manual.
As Castle ESC:s throttle calibration is very different to other esc:s (actually not possible to calibrate but need to calibrate tx to match esc) it gets really confusing when try set endpoints match with MC between tx and esc. If someone finds a solution please let me know. I guess we need to first try calibrate MC channel alignment with "wrong" endpoint settings but it's just a guess what the endpoint settings should be in this state to make this work. Then find real endpoints in throttle calibration mode and after that redo channel alignment again with right settings.
