No current plans, but I would be willing to do it given enough
interest.
Anybody besides Robin interested? Is the port spacing for the third
rotor the same as for a two rotor?
UPDATE: I visited the machinist this noon. He is half done doing the
NC
programs. I forgot to ask about the tooling/fixtures. He said he
expects
**some** of the parts to be machined by Monday. He found a shop to do
the
PFTE (Teflon is a trade name) as they have the experience and would
probably
be cheaper. Also waiting on materials.

Doc,
Yes, I would definitely be interested in a 20B slide throttle. I know
of one other person that has expressed an interest.
Mark Steitle
Lancair ES/20B
I'd be interested in the slide throttle for the 20B. My plan is to use
a 20B for a BD-4C. Finding the engine might take some time though as I
have not started the project yet.

I have put you on the list, Allen.
I guess I will have to talk to the machinist about flexible tooling, and
fixtures. NC programs will have to be modified too.
