I tried switching the motor wires and that worked but now I'm not getting any pitch on the blades. I am starting to think the 4-in-1 has something wrong with it unless you guy's can give me a better idea.
Q: Are your other servos moving at all?
Silly question, but are you sure the 4n1 initialized? Solid green light?
Also, can you confirm that you tried unplugging the main motor and tail motor, let BCP initialize (making sure you're not in idle up mode) and then moved the throttle up and down to check the pitch?
