Re: [FlyRotary] inline twin engines?
  Something like this ?
 This is a twin setup that I played with, the front engine is a 670 Rotax snowmobile engine that puts out 125 hp.
 Had a sprag clutch on the Rotax and just used it for takeoff and climb out then shut it down, the Mazda had a dog clutch so I could disengage it if it blew, would not hold level flight with the Rotax but at 10,000 ft I could stretch about 80 mile glide out of it.

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 ?
