Sorry for not updating this right away, but right before the maiden flight I did a throttle run up, and it was running really smooth until at full throttle the prop, spinner, and collet flew off the plane, taking some of the cowling with it. The collet slipped, and one of my field members recomended just getting one of those adapters where you grind a flat hole and attatch it with a grub screw, that way it doesn't fly off. Does anyone happen to know the name of that? here are the images, I'll have to repaint the cowl, and I already got 2 replacement props.
