I have a brand new YS 91 FZ. It will fly on an 8 pound fun fly. Can I fly a 16 inch prop? Most people like this motor with a 15, but for a large fun fly, a bigger diameter is usually better. How big is too big? I'll fly Wildcat 20/20 fuel and I'm at about 600 ft above sea level.

I was thinking a Top Flite Power Point 16x6 or maybe even a Bambula. I assume that a lighter wood prop would help transition a bit.

Thanks,
