I dont know if this is the right place to post this, sorry if it is not. I changed my naze32 rev 6 running latest betaflight from fs-ia6 running ppm as after a crash signal was weak, antennas seemed fine but it cuts out either way at about 20m, swapped to an old fs-ia rx and changed to pwm, after id swapped the rx and bf settings to pwm, all worked fine but one motor, found it was a broken signal wire on the esc for motor input 4, fixed this, span the motors up and now 1-3 do not work, wiring is fine, setting on bf are as should be, tried re-saving multiple times but can not for the life of me get the other motors working, its a different profile on my tx, not running ppm and its stil set to pwm signal, i came here as ive only had great luck with betaflight, love it and love the work Borris and others have done and wanted to confirm it was an issue with the fc and not bf. what could be causing motor ports 1-3 not to work, not in betaflight or via rx, i have tried everything i can think of and had no luck, so i hope you would be able to help as im getting itchy fingers ;) thankyou for any support
