RE: Moving up to Aerobatics
Don't be fooled by the high wing of a stik, it ain't no "boring" trainer. It's way more aerobatic than any trainer. It has a much faster roll rate and has no trouble at all flying inverted. Rolls, slow rolls, 4-point rolls, no problem. Inside loops, outside loops, no problem.
Weaknesses. Not the best knife edge flyer in the world. With that long tail and large verticle stab, it resists spins and flat spins. Great for keeping beginners out of trouble but not so great for people who do these things on purpose.
Ground handling as a taildragger is so friendly that you shouldn't even bother trying to make it into a trike.
