For a radio I am planning on the 9caps, which seems to be the best futaba for under a grand (the 9z or whatever was $1200 I think). I am almost positive it has several mixing functions. I'm going to wait until I actually get part of the plane built before I buy an engine. If a twin will fit, I would gladly pay the twice as much that it will cost, but the 1.60 or whatever is around 7 inches across, 4 deep, and 3 high, I think. Since I don't have a real mental picture of exactly how big this plane will be, I can not yet determine what will fit. It would be great to have the cyls out the side like the real thing, but I wouldn't want to have one real one and then two fake ones on the other side. I think that I could live with two real ones, but only because they don't make a 4 cylinder small enough. And Khodges, that looks really nice. I was actually thinking of doing an L-4 like that, but I then decided that since I have access to a real cub, I am going to make it just like that one.

BTW, nice nose art

Edit, I found a Saito twin that was 1ci. Can anyone tell me about this? Good power, reliability? Does it have the twin carbs, because I have heard that those are a real pain. Also, who sells them? They seem alright, the OS just looks so much more like the real thing, and it has twice the horsepower being only 60% biggger.
