David,

I have long ago quit trying to pinpoint delivery dates for aircraft
products.

I have made a fool of myself too many times doing that.

Until it is finished, we won't know what it will cost, either.

It should be available at the beginning, or rapidly thereafter, for
virtually all TCM and Lycoming fuel injected engines, turbo and normally
aspirated.

It should be under 10K.  It looks like, right now, it might be under
7 or even 6.  But I really don't know for sure, yet.  There are some
components that are expensive and that are real price drivers,  and some of
our pricing on that is still up in the air.   It should be essentially maintenance free from TBO to TBO.  So far,
there is only one life limited component.  It is not even a critical
component, but it should go about  2500 hours and about 150 bucks to replace
it at overhaul time.

We are working hard to deliver this thing for experimental use this
year.  But that can change, too.

It really should be transparent to fuel.  You can have a half tank
full of 91/96UL and mix it with 100LL,  or vice versa, and the engine and
you, will never know the difference.  In that sense, it affords a highly
transparent ability to make the transition from the present to a future
unleaded fuel environment. Regards,  George
