So to get the equivalent power from a 4 stroke that my OS 95AX turning a 15x6 prop is making, I'd need to go with at least a 1.2 four stroke? Maybe more?
If you want to go faster with your Big Stik 60, yes, youll probably need 120 or bigger 4 stroke to equal your 95 AX. However, I had a Saito 100 on a nine pound 4*60 that will dang near rip the firewall off of it running a 15x6 and will go unlimited.
And it sounds cool!
The Saito 100 is now waiting on me to finish my BUSA Fokker EIII Eindecker 90. I'd rather cut my leg off than put a 2 stroke on that plane.

And Ill be running a 16x4 prop.
I don't think enough emphasis was put on the "And it sounds cool!".
4 STROKES SOUND COOL!!! That wasn't important to me when I started flying. I couldn't see spending the extra. Now-"COOL" is part of every decision I make in flying-BW
