JD, I'm glad that you had such good luck with that prop... that 10x4 would probably be more comfortable on a .25, I think...

As for your wing bolt, check more closely... look for some cracks in the wood or a loose mount... I've had 3 Twist 40's (two are still flying) and none of those showed that 'looseness' problem.

I'm having fun with mine... both of 'em
