YS 140 Prop Size?

       Remove this ad - become a site supporter!
I recently picked up a YS140 four stroke and I was wondering what prop size to use? I want to keep the speed down and have some power for verticals. The instructions say use a 14X14, 15X12 or 16X11, at 9000 RPM these all produce speeds of over 85 MPH. I would like around sixty MPH. The aircraft is a Zlin Z 50 for a 120 2S.

We run a 17x6 Vess on ours with a Slimline pitts exhaust. Great combo with 20% Nitro!

I run an 18x6W APC on mine .It pulls the Dave Patrick Ultimate around just fine on Omega 15% .
The engine is the heart of an airplane , but the pilot is it's soul .
