That would be pretty cool. Wasn't someone talking about a turbine Chipmonk?

That’s what sparked the interest. I’ve been in talks with the engine manufacturer.
I bought a 182 and started a club with it instead.

Club?
I wonder how many of those RV-10s are built now. Looks like a pretty great unit. Probably can't import those either. Oh Canada.

So what kind of money are they asking for the engine? Sure looks like the sweet spot for power in a home-built airplane, thought i choke a little at the 18GPH fuel consumption at cruise. 
Looks like the same gas generator section as the engine on the Sonex jet.

L39 is 70 gph at idle, 300+ gph on takeoff. When we had two of them waiting for a buck fifty
on final at 50 knots, we were burning 140 gph on the ground.
Pro Tip: Only go turbine if you own a refinery!
Both the L39 and the C421 were about a thousand bucks, each trip to the pumps in Canada.

My very rudimentary understanding from ground school is turbines switch to more efficient over a long distance when you go fast enough.

I had to sign an NDA with regards to financial info. But, I'll say this: it's not cheaper...
Turbines are efficient up high, in thinner air. The savings is in they still work in the thin air, whereas you'll need one hell of a super charger for a piston. Just a guess, but thats why the Allison's boost in the 50" MP range.
The idea for me, is the RV10 is dime-a-dozen. Why not make something really unique?
The club idea came about because I received constant attention about owning a plane, but then got in to the $$ details and people were turned away. I have 2 coworkers that fly the plane when they want, for a fraction of what the local school charges for the 172. My insurance is set up for me plus 3. I have another coworker asking permission from his boss, hopefully she says yes, and all the members will be coworkers of mine.

Understood! I just looked up the PBS TJ-100 on the Sonex website. They're asking $60K and change if you order it with the Subsonex kit, and $65K "regular price". Adding the free turbine spool and a gearbox, I'd make a wild guess would add another $20K to it, or more.
Nice little pipe dream, it'd be a hoot for sure. ;^)

Sharing an airplane is like a marriage. Need to choose the right people
or you're going to wish you never did it.
