Hi. I have built the 250 cheep version that Bruce put on youtube but I have a problem motor 2 spins up faster than the rest when using my tx. I have set the ESC's as per the youtube vid 14 times and all though when I use Baseflight software all 4 motors work perfectly. but when I use my tx number 2 motor flys up faster than the rest and I am comply overwhelmed as to why.
Any help or guidance would be appreciated.
