I 've got a like new OS 120 twin four stroke that I purchased in hopes odf using in a 1/5th scale Waco YMF-3, but I think it would be underpowered after looking into it a bit more. SO I'm looking for suggestions for a different aircraft to use this motor with. Because of it is so wide, it's not a natural fit for too many planes. I really don't want to do a Cub, I love biplanes. Any suggestions out there?

Sig Four Star 120 would adapt well to this engine and have good performance

A sig spacewalker II would be nice.

I agree. The one 1.20 twin was used in one of Sig's prototype models. It's a natural for the Spacewalker II.

It's a well designed kit that frames up without too many headaches.

I have an original OS 120 FT Gemini twin in a Bud Nosen Champ. The plane is very heavy at 15lbs and slightly under powered but flies very realistically. I try not to push this engine too much because I have heard they have weak push rods and spare parts are near impossible to find.

Hello; If you like biplanes, a Bucker Jungmeister, or a lazy ace, I like the spacewalker idea also. I also agree with the "take it easy with it" philosophy as I have an early gemeni that broke it's crankshaft. Parts are unavailable and therew isn't much knowledge out there, My Spacewalker has a Saito 120 in it, so a Gemini might not be quite enough, depending on your altitude.

If you want realistic scale flight, a 1/4 scale Cub or Aeronca Champ.
