That 2 min glue job I did in the above pic shows how a mod can be done to make turning twice as sharp with a piece of plastic I folded and glued the both sides of the rudder. Now I can do figure eights+ where I couldn't before. I do have a 60 foot of straight to get it to climb so thats ok, I guess I could bend back tail tabs up to help with the climb which I haven't tried yet. I like it!
