The gear is fine. My first one had an off field excursion and the gear stood up well, it just has the right amount of flex to make all your landing glass smooth. The GP Ultimate uses the exact same gear, except for the color and that plane weighs 15.5lbs (I have it as well) and I have harrier landed that one a few times with no problems

Oh year, the gear is a fiberglass resin so if you do see any cracks or chips it is usually the paint
