RE: CMP Quest 50 ARF----????
the cut lines is to line up your motor just offset from center. the firewall if your looking at it u want to line up the center of the shaft of the motor to the line just right of it and make sure you have 2 degrees down and 2-3degrees to the right that you would give you the best for flying straight! are you using a fourstroke or 2 stroke engine for this plane? if you have any more question rite back.
