The Spit is still hanging safely on my wall, and I've been flying the Super Cub. Actually the Super Cub almost flys itself! I've got 70 minutes flight time on it, and haven't crashed hard yet. I broke a plastic wing strut and cracked the cowl on my first "landing", but no other crashes. I now see that its going to be a while before I can handle the Spit. If you get into trouble on the SC, it self corrects pretty well, and I know the Spit will not. And it goes faster, so trouble happens quicker.
I will probably add ailerons to the SC and learn to fly with them before trying the Spit again.
