RE: cox control line planes
One of the guys had a newer surestart PT-19 a few months ago we managed to actually get in the air. It was pretty evil handling. Tail heavy and I had to whip the crap out of it to maintain any control at all.
I got a Stuka sitting in a box, but it'll probably stay there for a while. That PT-19 was one of the hairiest flights I've had in a while.
