YS 60’s “Round Head”

Props from 11/8 to 11/11 should be fine considering your airframe (Bridi Escape/XLT)

This motor will work well with various props and pitches, depending on what you’re after as far as performance.
“Ballistic with low pitch, quieter with high pitches.”

Here are some rpm figures for the YS 60

You’ll be very happy and surprised with this motor Orlando.

“Most powerful 60 size production engine ever made in my book”

My Favorite fuel assisted motor.
