So... I caved and for my first plane got a hobbyzone super cub. I love it. I've had it for about a week and despite some wind have only ended up in a tree twice. Anyway, flying with my assistant (6 y/o son), and he slipped while walking up a steep hill cub in hand. Here's the damage. I am thinking of getting a couple of foam plates to cut out a new rudder, and maybe build up the damaged bit of the tail section with heavier foam.
