ok, don't worry. If you are at the level to be flying this plane then it will never be a problem. I am 15 i have this plane and i've had not problems with the landing gear mount. The gear itself sucks, it will delaminate eventually but horizon sent me a free one when it happened to me so it was cool. but the plane is pretty strong from what i've seen of mine. It flies great and you'll like it. Don't worry about the strength of it. If you want you could slap some fiberglass over the landing gear block but i wouldn't bother.

My setup is

Ys 110FZ motor
Apc 16 x 6 prop
Morgan Cool power 25%
Hitec 5625's all around except
Hitec 5945 on rudder
6.0v 2700maH battery
Jr 790 synthesized pcm receiver
Jr 6102 radio
