naswifty, I threaded my excess antenna through my tail wheel spring (Sullivan) then taped it to the bottom of the rudder with shipping tape. If you are using the provided tail wheel assembly, then maybe you could just tape it to the rudder anyway. I'm right at 5" (measured with the Twist inverted on the test jig), and it flies great and the tail sags at low throttle for an easy 3 point landing. Try a couple shots of Wild Turkey before the maiden to calm your nerves. Just kidding. I predict everything will go fine. The Twist is an easy plane to fly if you stay with it mentally. No day dreaming about the big fish you caught last summer.
