Re: Modern Engines on Q2?

Ryszard Zadow

The original Varieze had a VW, which like most that try an auto engine, got changed to a Continental. 

If he’d not done that I doubt it would be the success it is today.

I’m glad that when many people told Mr. Rutan that these crazy looking airplanes couldn’t , wouldn’t , shouldn’t fly, that he didn’t listen to the naysayers and continued on.

What Ryszard said.

Also depends on your ambition and appetites for either flying or long term R&D….

Show me any auto engine conversion that made it to 2000 hours. 

Auto engines don’t fly. Everyone i’ve known or heard of that’s tried went down one of three paths:  

1) Eventually went back to a Continental or Lycoming and flew happily ever after, 

2) It became a hangar queen. 

3) It killed them.

No. No. No. Revmaster is a very well engineered adaptation from few Volkswagen components with aviation born crankcase, forged crankshaft design. Sharing cylinder and pistons, con rods, Revmaster is very well thought out adaptation. Weaknesses in early magnesium crank cases have been mitigated with an alloy crank case with a 7 pound penalty. Notwithstanding, the current state of the art is likely the best offering of all other aero engines based upon Volkswagen components.

Curious what modern engines people have put on their Q2s for upgrades? What else beside an O-200?
How about a Rotax 912ULS?
How about a UL260?
Which car conversion engines have been popular with the Quickie community?

Yes I know this is a controversial topic with the hard core aviator but please humor me and share what people have used, not your thoughts on how good or bad a car conversion is ;-)

Thanks Robert

Love building planes almost as much as flying. Latest completed build is "Loki", a Chinook Plus 2 bush plane.
