I've had 3 or 4 of the 46's and a 60 and the only time they have come apart is when I smashed them into the ground. They are really fun planes but not top notch 3D planes. The Saito 82's are right at home on the 46 and the 60's do well with the YS 110's and Saito 125's. The key is not to fly them fast. The will disintegrate if oversped.
