Default 1/4 scale cub engine? Which one?

Just wondering if anybody knows of a good engine choice for a 1/4 scale cub. Preferably gas/twin. I know the OS160 is an excellent fit, but are there any gas models like that?

The only gas twin anywhere near the OS160 is the Saito 57cc gas twin which is far too large for the 1/4 scale cub.

I had a cub with a DLE30 in it and loved it. I put dummy engines on it for looks. Just wondering if they make a gas twin that would work or possibly a gas conversion for the OS160? I found an amazing kit that sparked my interest.

Since the full-scale cub has a four-cylinder engine, I don't understand the draw to have a twin. If I did anything like that, I would go for a 3-cylinder radial and mimic the Lenape engine that some Cubs had...

I have not seen that one before. The only reason for a twin is it looks closest to the real thing without adding dummy engines. I like a gas engine mounted inverted with dummy engines the best.

What 1/4 scale Cub and how do you want to power it? Are you going for Bill Hemple-style 3D-with-a-cub overpower, or good sport power for scale-like application? I've got a SuperCub built up from the 1/4 scale Balsa USA kit - 111" wingspan, I believe - that flies just beautifully with a Saito FG-36. I would think that 57cc twin would be FAR too large.

The closest thing to scale I've seen is the OS "Pegasus" 3.20, but it's a bit large. If you can find one of the really old models, I think they were like a 2.70 that should put it about right for a scale 25%er.

Otherwise, use the flaps, put an enclosed cowl so the jugs don't show, and call it a SuperCub!

Default rcgf 40 twin

Hope this helps. Might be a bit big though. Also too early to know how well it will work for ANY application, but so far looks good.

I love my Saito FA-200. Like, NO vibration. But not gas.

most cubs wont have much cowl left after cutting to fit a twin. on my bench right now is a sig 1/4 with a dle 35 ra in it. cowl was not cut other then the bottom for air. going to be way more power then it needs but needed the 35 as its had the rear muffler
