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 ......

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 ?
