RE: Cub As a trainer
High wing taildraggers with light wing loading can be a real bear for ground handling. The wing likes to fly before the tail does, which can be a real problem to someone who's not accustomed to it. Barn-door ailerons may not respond as fast as expected, and they can do funny things in flight. Like the wing that wants to fly before the other stuff is ready to get airborne, the ailerons are yet another glitch that needs some getting used to. The Cub has one saving grace that my Tango doesn't: It's not as twitchy. I'm serious when I say, a Cub ain't no trainer. A second plane, maybe, but preferably a third or fourth. But not something you would want to learn to fly with.
Get yourself a trainer, and mount your engine and other stuff on that. Find an instructor, or get a simulator and lots of space away from people and property. Master that first. Then the Cub, maybe.
