Default Push-Pull Speed Plane idea....

Don't know what made me think of this.... must have been from looking at pics of a Dornier DO335 Arrow and a Cessna Mixmaster.....then I started looking at my Patriot.....

So, what about building a push-pull powered Patriot type plane.... say with a pair of 46's powering it, one in the front, one in the tail.

This would give a plane of approximately the size of a Patriot the power of a 90, give or take a bit. I've always been fascinated with the inline twin design and (the Arrow and the Mixmaster being my favourites) and it has definite advantages over a "regular" twin design.

Anyway, just wanted to throw that out there and see what your thoughts were!

Thanks,
Steve

You could try this fairly inexpensively, and it might be interesting. The thing is... If you use an engine like an OS .46FX, and say, a 12 oz. tank, you're going to add about 2 pounds to the airframe, at least.

Yes, and WAY behind the CG so in reality, you'd end up making it a lot heavier just to balance it.

You could however, lengthen the nose or move the wing back but then those are some major mods if you're talking about doing this to a pre-existing kit. Better to scratch build something in this config.

the cesna 337 idea may work since fuse is short and 2nd motor would not be to far behind the CG
