the plane is strong.
but the plane is also built light with competition in mind. so it can actually take a good hit and it's easilly repairabel but eventually the plane will go. which actually is a good thing because each one you build you build better.
You will not jerk this plane apart in the air with a .32 engine. and you will hardly ever be flying at full throttle unless you are pointed straight up.
use the carbon fiber on the main spars though, it helps alot when you hit down onthe wing tip.
good luck .
