Oh almost forgot.

My spinner has developed a crack at the lip that hold the spinner into the back plate starting at the prop slot for about 3/8" . Also the holes in the spinner for the screws I have, were drilled bigger to allow the 8x32 easy fit. The holes have cracked. If making an alum backplate try to avoid enlarging the spinner holes.

I think it was due to the nose over shown on the vid. I'm surprised the minor nose over caused the damage. I have nosed over many model with plastic and composite spinners in the years and have not really had this kind of damage.

Again, rev up in an area clear of people and yourself in case it flies apart.
