I'm interested in buying a super cub wide body kit, wondering if some
of you have any bad storys or good ones about this aircraft. I want to
put a O360 for a motor and run on floats in summer and skis in
winter. I'll be waiting for you comments.

That would be my third plaine, I flew ultralights with 912 rotax, now
I want someting safer and with more capability.
