Only thing that broke for me was the top of the rudder. I think I was doing some bit fast knife edge, and the top just folded over. I insserted a carbon rod and glued kevlar tape to the outside. The fuse held up well, didn't have any joints come unglued, and I did do harrier landings with mine. The new one will have a large (taller) composite under carriage, since I'll be swinging a 24x8 prop after break in of engine. Also, stock gear put the plane pretty flat, and it needed some ground speed to get in the air - I want it to just jump in the air.
I spent time and energy double bevelling the rudder and elevators on my first one, but I'd like to hear opinions on whether beyond 40-45 degrees of throw is actually beneficial.
