Well, I apologize for that. I've not been able to find it. I do have one that shows different props for different engine sizes, but that's not what you wanted. Maybe that is what I thought I had and thought it was plane vs. engine sizes.

But, any 60- 75 size engine or larger four stroke, up to 90 I guess, would work for that plane, although I am not familiar with four stroke engines, Minn specified what engine for a Cub.

If this is a new plane, well, take a close look at the manual and decide what range you wish to fly the plane. Keep in mind that recommendations can be a tad bit deceiving, perhaps that is the reason for your question.. but you can't go wrong with what I recommended in my first reply, the OS .75 AX will power just about any plane in that size and weight category, I promise you that.
