Default Best prop for an OS91 on the Cermark F-18

Hello,
Just wanting some info on the best prop to use on my OS91 installed on the new Cermark F-18. I only have 7 inches from the ground to the center of the engine shaft with the original nose wheel installed. If I install a 2 1/2 inch wheel, I have 7 3/4 inches. According to the OS manual, they recommend a 15 inch prop which will not fit. I guess I am a little worried about burning up the engine with a prop that is too small.

Any input is appreciated

By the way, a very sweet model.
I was sent the wrong nose wheel (to short) and my kit was missing the spinner but Cermark took care of me and shipped them right out.
I cant wait to get it in the air.

Lonny
