Hi everyone. We are in the process of repairing the rear fuselage structure of series IV speedster (80 hp) that flipped on its back on landing. Kitfox does not provide blueprints or measures of the steel strut, so we will have to eyeball some dimensions, relying on the remains of the damaged structure. We are not particularly worried of the top view (overall length, etc.) but the incidence of the tail plane might be critical. Could anyone tell us what the incidence of the tail plane relative to the wing should be? (or vice versa,...). By the way, the elevator did not seem to provide much authority on final with flaps extended. Is there any mod recommended for the tail rigging (short of enlarging the stabilizer, which I understand somebody has done)? Thanks Piero
