It's hard to believe this was 32 years ago.

I think he got wrong and really referred to OS Engines FT-120II Twin Gemini (not Genesis....)

Yes that was my guess also, but then I am thinking if a OS FT120 twin would be enough for an Ultimate...?

Hello, everyone. Has anybody flown this plane with a Saito FG-21? I've gone through the whole thread and only saw one person that used one, but they never came back and said how it flew. I'm not interested in 3D or hovering. If it would fly as good as my GP Super Skybolt with an OS 1.20 four stroke, I would be happy. Thanks.

I'm not sure if I was the one who mentioned flying mine with a Saito FG-21, and not following up here. If so, my apologies. It flies awesome with the FG-21. It won't have unlimited vertical, but close enough. And it'll just sip fuel!! I had a GP Super Skybolt years ago w/Saito 1.20 and I'd say it's a similar experience so you should be happy.

Thanks for the info! I'm just getting into gas and I've been reading that they're not as powerful as the glow 4 strokes so I was curious if it was that noticeable. Thanks again!

Same here... been into gas now about 3 years. They are a little less powerful than their glow counterparts of the same displacement, but not by a major factor. IMO the fuel savings, efficiency, and lack of a greasy mess to clean up afterwards far outweighs everything else. I do love my glow engines too, have several of those too, and each has it's advantages.

vogelm1, if it's not too much trouble, could you tell me where you put the ignition box or take a picture? I need to do some more research on what setups people are using as far as batteries and Bec's and their placement on these smaller gas planes. Thanks, Jim

Unfortunately I sold the plane about a year ago, and also don't have pics of the set up. But I recall placing the ignition either next to fuel tank (you can get by with a much smaller tank by the way - think I used a 10 oz and was plenty), or under the fuel tank floor. I used a separate battery pack to run the ignition (so two switches, one for receiver and one for engine). But if I was to do it again, I'd just shave the weight and hassle, and use a Tech-Aero Ultra IBEC. Used them on several gas planes now up to 50cc and they work really nice. Don't recall any balance issues having the ignition way up front either - the box is pretty light.

You are probably right about the original being dark blue. All of them I built I used Sky Blue and the ARF I had later on from goldberg was sky blue.
