(This is my last post for today, I promise.)

I was having no end of trouble with the backplate of my Goldberg (4-pin) 2.5"
spinner slipping (APC 11-6 prop, OS 50 FSR motor). It didn't help that I needed
a spacing washer between the drive washer and the spinner backplate to give
cowl clearance. I tried everything, roughening the surfaces, cutting grooves
with my dremel tool, etc to try to increase friction, but I still could barely
even tighten the prop nut without the prop slipping out of position on the
backplate. When I did think it was right the prop would still come loose after
one flight.

I finally hit on the idea of throwing the dremel tool away, but keeping the
thin cut-off disks and putting one on each side of the spinner backplate. These
things grip like crazy!

See you later,
Max
