I am putting a YS 110 on an Extreme Flight Yak 68. Many people have used APC 16x6 and 17x6 props on the Yak with this engine. I know the manual says to use the prop you plan on using or one slightly smaller. I just wanted to check and see if I break in my YS 110 with the APC 17x6 (the prop I am thinking I will use the most) if that would be okay and not hurt the engine.

Thanks in advance.

Won't hurt, but I would use a 16x4 for break in.

Thanks for the input Dave!

Good flying!
