RE: GP GEE BEE
rudder diff
reason --cheeper/easier---but wrong
fixed mine by bending up a sheet aluminum horn and mounting it inside thr rudder with sheet metal screws from the outside and bored a hole through the rear of the fusealage for push rod/horn clearance.the horn to pushrod joint is on the centerline of hinge now and when right rudder is aplied the horn moves into fusealage--hope this made sense.
looks like it will be alittle while befor i mount engine/radio as just bought out another machine shop and have to add onto shop.
