RE: GREAT PLANES FLATOUTS
Problem is definately in the lingages. Must be totaly free. Before you glue the hinges/ect to the plane, use a drill bit to drill out the holes. Slide the hinges onto the graphite shaft before you glue them on th check for any tightness. You should be able to flick the hinge with your finger and it must rotate several times before it stops or it is not free enough. Forget about using the hobby knife, use a drill bit for all points that will be used a pivot point or hinge.
