RE: Sig Kadet Senior
I made mine a taildragger with no problems.
It did make it a little tail heavy but that was adjusted with a little weight in the nose.
The only major change is repositioning the main gear forward. I placed mine so that the center of the wheel was inline with the leading edge of the wing. No need to change anything else.
As for control, I like taildragger better. Tail wheel or nose wheel, you steer with the same stick.
