Thanks Mars.......there are only a few of us that can really appreciate the fun of a Speedy Bee. I like being the only guy at my field who has one.....and everyone likes it but they say they want to stick with the ARFs and that it takes too much time to build a kit. Too me building is fun!
You are having problem with the rudder? In the air, is it mooshy? Before you fly, with the wing off the fuselage, try holding tension on the rudder and with the radio, move it left and right while looking into the fuselage at the control wires. There may be deflection with the the control wire. They need to be anchored down and anchored down well! Sometimes glue does not hold. I have wrapped thread around the wire housing and structural parts of the fuselage to cut down on the deflection in my other Bee. I learn my lesson after my old Bee would not respond to the radio when it would not come out of a dive. That is why I put my servos in the rear with short rods instead of those long wires and plastic tubes.
