<div></div><div>Not sure where to cast my line so I will try here.</div><div></div><div>Hi all, I wanted to ask the greater pool of experience on an engine for my Sig 1/5 scale Cub. I will be starting the build as soon as the kit arrives. I haven&rsquo;t settled on an engine yet, way to many to choose from. I would like it to remain somewhat scale in performance leaning on the side of a little more power, but I do not want the engine to look too big for the plane. I would like to go with a 4 stroke, and I have considered a gas engine also. So I throw this out into the great RC universe to see what comes back, I imagine that you all will have a much better take on what to use then myself.</div><div></div><div>Thanks</div><div></div><div>TB</div>

I have a Saito 56 on my 1/5 scale Sig Cub and it is a perfect combo. Just the right amount of power and the the little Saito will fly it for 30+ minutes on a tank of fuel. You will enjoy building that kit.
If you want a gas powered Cub build the Sig 1/4 scale and put a Zenoah G26 on it. They fly great too.

<div></div><div>What about a Saito &ldquo;82 Golden Knight AAC&rdquo; ?</div><div></div><div>TB</div>

I'd go with the OS .72 FS alpha. GREAT engine and probably give you as much power as the Saito .82 (which is also a great engine). If you think you would ever consider putting floats on the plane go with the larger displacement. I've had that plane for 8 years and she flew well on an old OS .70 Surpass but when I put her on floats I moved up to the .91 Surpass. But then I'm at 5300' elevation.

In any event, stick with a 4-stroke from OS or Saito and enjoy your Cub.

You wanting to fly it like a Cub or 3D it?

One of the new 20cc EI gas engines would be the cat's arse.

I had the OS .70FS and it was a lot more power then needed. I don't think I would go any bigger then that.

<div>So the 82 are too much engine? Then the 56 should do. I will pull the trigger on the 56 and forever hold my piece, thanks all for the input.</div><div></div><div>TB</div>
