Two .46 engines... what size plane?
I have one OS LA 46, working on getting another. would these be crazy to strap to an LT-40 kitbashed to a twin with a beefed up wing? Would the extra weight required balance things out?

Not only the wing but the tail and rudder as well. Don't know why you would want to put that much power in a plane the was designed to be a easy to fly trainer. You would be better off installing a pair of .25 engines.

Well, honestly because I'm just trying to work with the engines I have... If there is a slightly larger kit I should try, please let me know.

These are all twin ARFs, I want to build something, and not a fancy warbird kit... Thats why I wanted to kitbash the LT-40.

Maybe, that looks like a beautiful kit, BUT I was hoping to bash something together so I'd have a cheap plane to play with, try out a twin, and get to custom build some stuff. Oh, and I'm halfway through building my second plane. I have a LT-40 in the trash (trainer crashed me grumble grumble.) I'm building a 4 star 60, and have a hog bipe to build too.

Why not do the twin conversion of the Hobbistar 60 that is in the current issue of Model Aviation magazine. It will take two 46's and, with it's 71" semi-symmetrical wing, it will handle the power a lot better than the LT 40.

I saw that, I just would rather do a kit than mess with an ARF. That way when I crash I've already had 100 hours of fun.

That would be sweet, maybe I'll build another after this one... I havn't started on the wing yet, but I have the fuse finished and set up for a Saito 91 FS. It would be nice to have one already built to be able to take plans off of for building the nacelles... Thanks for the idea!

RE: Two .46 engines... what size plane?
I think the LT-40 will be fine. I have a pair of OS .46LAs on a twin and they aren't going to pull the wings off unless you start doing crazy things which would probably kill the plane on a single engine. You are talking ball bearing .32 power here. I like a 10-7 or 11-5 prop.
I would strengthen the center wing and add some bracing wires on the tail. If you get the CG right, I'd use weed eater line. I use that a lot on planes. It weighs next to nothing and will keep your tail from breaking. If the plane is nose heavy, I'd use 2-56 rods just for the extra weight.
On the LT-40 with extra power, you'll need to shim up the trailing edge of the wing. I would jack it up 2 popsicle sticks or about 3/16". This should keep the plane from climbing at full power.

Goldberg makes a .60 size trainer kit that I am thinking about kit bashing into a Twin Otter, that size should take two .46's easily enough.

I have done a couple kit bashes of 60 size, old style pattern planes (Midwest Strikemaster, Kaos, and Direct Connection Sea Fury) I added 12 to 15 inches to the wing center section and used a pair of 35's to 46's. All flew great.

Try the AeroCrafts Gemini GT-40. This twin is designed for .40-.46 size engines. Excellent handling. Look for it at www.aerocrafts.net.

how about a ripmax harmony twin

Orygg, do you have a pointer to a L-200 Morava kit or ARF or something? Neat looking plane there.
