I started with a Kadet Sr. from a kit. bought it used and went from there. It originally had a 50 Saito but then went to a .91 OS 4-stroke. Also my dad built up another wing for it with a lot less dihedral and gave it a little gull-wing effect, like a Stinson Reliant (that I will have one day). I LOVE this setup and recommend it for anyone learning to fly.
