Re: what size prop

Your max range is 5500 rpm. Looks like you have a OEM 15" prop. Go to miwheel.com for their numbers. At comprop.com they recommend a 13" prop #M4323

Re: what size prop

If you are running a 15 pitch, I would up to a 17 pitch. 13 pitch will put you over 6000. A cupped 15 will bring you down a couple hundred as well.<br /><br />Good Luck

Re: what size prop

Sorry bones I misread your posting.<br />A 15" cupped should bring you down to 5500rpm A 17" should take you down even a little farther,but close to a 15" cupped.

Bones a 15" prop that's not an OEM will even rev higher than 5700 rpm.
