I really do like this frame, but it needs a v2 arm without the little cutout on the inside, broke just hitting the dirt in my back yard, no rocks or concrete, luckily mine came with soare arm, but later broke another hitting a tree branch, both broke the same way, this would be my favorite frame if not for that issue... So now it's a wall hanger for now till i can get arms that don't fail so easily and I'm back to flying my Demibots.....
