Default RE: kadet senior tail dragger question

When I did my Kadet Sr. tail dragger conversion, I decided it would be easeir to mount a micro servo in the tail than to rig up some sort of long linkage from the cabin area, and I wasn't excited about hacking up the tail to connect the tail wheel to the rudder somehow.

I connected the servo arms to the tail wheel with springs so I could easily use a low torque micro servo without worrying about shreding the gears.

Both rudder and tail wheel servos are driven by the rudder channel using a "Y" harness. You may notice from the pictures that I reinforced the servo and tail wheel mount area with some light ply. This has held up well with the exception of the one day I was out in 20+ mph winds. The rocking action on the ground from the wind gusts worked the tail wheel mounts loose. I put in blind nuts and haven't had a problem since.

The only down side to this is that it came out pretty tail heavy and I had to put a fair bit of lead up front. On the plus side, the Kadet is already so light that it doesn't even really notice this extra weight. With my 61-FS at idle, I can barely lose altitude unless I slip or force a dive. I flew this winter and in the sub freezing temps, I literally could not land until I killed the engine. This is the most stable, gentle, predictable aircraft I have ever flown.

Just as an aside, I really love flying the Kadet Sr. in high winds. You might have to walk it to the take off starting point, but it is fun to need to put it in a 1/2 throttle dive just to fly a landing approach and not get blown backwards! I've flown a vertical approach matching my airspeed with wind speed and touching down with almost no forward motion. (Usually the wind is lighter right at ground level so it will surge forward a bit right as you are flaring and touching down.)

I have as much fun with the Kadet as I do with any of my hot-dog airplanes.

Curt.
