I didnt know that you shouldnt use quick connectors on control surfaces. I am using them on my SPAD 40 , but I havent flown it yet. Maybe I should change to clevises. Im not too worried about my SPAD crashing though. Its a very tough plane. Is it all right to put a spot of glue or thread lock on a quick connector to keep it from loosening? These connectors seem to be as strong as clevises and make it easy for me to make adjustments at the field.
