Prop Recommendation
 
I am building a World Models Zen 90 and I intend to power it with a YS 91 AC. Any suggestions for which prop to use would be greatly appreciated.

Thanks,


Rob

Propping the YS91AC/FZ
 
Rob,

I have had a few, and still have 3 YS91ACs. The YS91AC will pull anything from an apc14x10 for fast planes to some modified Zinger16x6 for fun fly planes. For aerobatic planes I like the apc15x7, it's a light load, so the engine is responsive. If you want a fast but responsive plane, you could start out with the apc 14x8, maybe apc15x8. This is all on YS20/20 fuel.

Prop Recommendation
 
Depends on the weight of the airplane. I would recommend a APC 14x10 if it weighs <8-1/2 lbs. Anything over that and go with the APC 15x8.
