Hi everyone, this might seem like a silly question but I'm having troubles.. I bought Spektrum's fpv quad serial receiver to use with a CC3D flight controller, and the first thing I noticed is that the wire plug from the receiver doesn't fit any of three pin plugins on the flight board. It's a little to big to fit into the main or flexi adapter slots on the board. I was wondering if this receiver can even be used at all, or if there's a different wiring I need to get? Any advice would be greatly appreciated!! Thanks!
