Status: offline 		The only thing that comes to mind is the Great Planes P-38 Lightning Profile Kit:

http://www.greatplanes.com/airplanes/gpma0487.html

It's actually designed around dual .15 2-strokes. I haven't seen anything else out there like this that is commonly available.

Status: offline 		Back in 1991 I built a twin for two OS Max 40FP's, the forrunners of the LA. I kit bashed a Johnny Cashburn Super Something into a Continental airlines Beech Liner. I flew the plane for 11 years and then sold it. I believe it still flys today. But, I will never put those engines on another twin !!!!!!! I literally had over 100 engine outs in that period. Some were non-events. Some were near heart attacks.
They will work, if your mind is made up. But you will be an expert at flying on one engine.

But to answer your question: You can find a kit or an ARC that is designed for a 90, then there is your wing. You can easily scratch the fuselage and then plant the original tail on it. Thats what I did.

Status: offline 		If you are a builder, I would suggest getting the Tower profile Mustang and converting it to a twin fuselage Twin Mustang. You would have to duplicate the fuselage and make a straight wing section for the center and a new stab, but this isn't very hard. I think the OS .40LAs will pull it very nicely. Just don't run them too lean.

If you are serious about twins, drop me an e-mail. My flying buddy, Flaps Laffert, and I have built 24 twins. I can give you a list of twin dos and don'ts that I published in my column.

Status: offline 		One of the newer design fun fly profiles would be a good match.

A Paul Swany plane like the taco or mojo would be a good candidate. You would have to buy 2 kits and modify them but they are such easy builds I dont think it would be that much of a challenge.

I am building a Fusion right now and I think a twin fusion would be fun too. It has a bit longer of a tail so might be better for a twin.

I would definitely build something with one of the newer designed profile fuses that uses carbon fiber.
