Erik: Yes, it's not only a Watson tail, it's Doc Watson's original. I bought his partially-completed Aerotec 'Bee kit back from him, finished and flew it. I later sold the Watson tail group, though, and made a 1/4" marine-plywood tail set, a la Bensen. Same general layout as Doc's.
Doc's location for the H-stab is about right, in my opinion. At that height, it receives the fastest propwash, and also is less blanketed when the power is off than a centered H-stab. Centered H-stabs lose most of their power when the throttle is closed, since the stab is immersed in the turbulent air thrown off by the pilot and engine upstream.
No, I didn't bend my axle tubes. Bending structural tubes sets my teeth on edge. Forces work in straight lines, not around corners. The 'Bee's 1/8" wall axle tubing is so massive that it likely doesn't matter, but bent tubes are just offensive to the eye, IMHO. To avoid the bending, I made and sold a machined insert for the axle tubes that has the necessary angle between the (steel) stub axles and the axle tube built in. I don't know if Starbee continued with that particular part design.
