Could anyone tell me the performance specifications of the original FS-120 (non-surpass) engine? I have a Dalotel built by Dick Hanson that I never put equipment in. The sister ship was setup with the first FS-120 and flys great. I was thinking, with the advancements in engine technology, I could use a slightly smaller, lighter, 4-stroke engine. I'm looking for engine weight, HP, RPMs, and prop sizes. I was unable to find the FS-120 on the OS website. I guess it's pre .pdf.
Thanks

The O.S. Max FS-120 Surpass E is the non-pumped version. You can find the specs at:

Just to clarify. Are you saying the FS-120S-E (OSMG0930) Parts listing [link=http://www.gpmd.com/cgi-bin/wgpprt100p?&I=OSMG0930]35530[/link] and the FS-120 (non-surpass) Parts listing [link=http://www.osengines.com/parts/xr35500.html]35500[/link], have the same performance specifications?
Thank you for your response

Sorry, missed the "non-Surpass" part of the original post.

We don't have specs for that engine any more. The oldest O.S. catalog we have didn't have specs posted. It's old enough that not even any parts are available for the engine from us or from O.S., in Japan.

Our best recollection is that the peak power output is about 80% of the peak power output of the non-pumped FS-120 Surpass E.

Thank You. That's good enough for me. That put's it at the power of a FS-91S II with a 7.6oz savings.
Thanks again
