I put one together with an OS 160. I never got it to flying very well because I was having trouble with the engine. There are several issues that a really a PITA. The springs to hold the wings on are a joke. Mine came out to 12lb 4 oz. I dorked mine when I went deadstick in a harrier. I got out of the harrier okay and thought I could make another turn back to the runway. I was wrong[
] I haven't decided whether I'll repair it or not. Wings are fine but bent the wing tube and tore the LG about half out of it. I think the firewall is also broke but I haven't looked at it yet.
