I had a Dazzler with a OS 46 AX on it and as was said in several posts flying too fast could rip the wings off. Luckly before the wings came off I noticed that the engine was literally pulling the fuse and wings apart. I added some epoxy and kept flying until I got tired of the plane and went to a Twist. The 46 AX is somewhat overkill too but I like overkill.
