OK, thanks for all the input. I am not going to try and tell you that I understood everything that has been discussed, but I did get out today, beautifult day - clear blue skies, 5mph wind and a cool 10 degrees! I did move the landing gear back 1/2 an inch and no more ground looping. Anyhow, the rudder control works, and I actually made some fairly acceptable takeoffs, not the prettiest, but a lot more stable..... until the last one! The wind started to pick up, so I had a little more right rudder, then she lifted off nicely, only to do a beautiful arc to the right, then continue on over to the ground! Spectacular cartwheel, fortunately only a broken spinner and a slight crack at the base of the rear stab. Thank goodness the wing is attached with rubber bands. I can certainly attest to the strong construction of the SIG Kadet Mark2!
