I think that is doable, add some glass on the inside of the relatively torsionally weak nose and sit near the back seat. I wouldn't bother though. The only thing that comes to mind is a twin EZ that uses two little jabirus or so. I don't think you would improve anything though. EZs cruise real nice at 12000 feet and from there you have an engine out glide distance of 25 miles, put a 50 mile diameter circle on you sectional, there ought to be a little airstrip in that range. I would actually bet that a Long EZ at 21000 feet has a better engine out performance than a Piper Apache that only lost one engine ;-)
 
Now If you would take the all carbon fiber Berkut and add two 3 rotor turbocharged engines at 350+ HP each you'll overtake a new King Air in climb and top speed ......

Subject: [FlyRotary] inline twin engines?

Greetings,
 
While I should be worrying more about finishing the Rev 2 FWF project on my RV-3, I can't help but think about what I'll do next.  I've always thought the ideal plane would be a twin engine, in a centerline thrust arrangement.  The only homebuilt that I can think of that fits this description is the Rutan Defiant.   For you guys that have backwards planes, how hard would it be to modify a Vari-EZ, or Long-EZ into a push pull configuration, using two single rotor engines?  Would this be relatively EZ (sorry), or a major effort?  I would be willing to set it up as a single place, flown from the rear seat if that will help with the CG.  Since I'm fiberglass challenged, I would be looking to buy a nearly complete project, and modify it from there.  Think it will work out ?
