  Steve or anyone know how much this system costs - a bunch is my guess.

  $2,860.95 is the list price from Airflow Performance for the 13B kit.

 Vlad,
 I can see why your looking at carbies.

That's pretty steep pricing, indeed.  Is it cheaper than the Lycoming
setup?  The rotary only needs half the nozzles and spider outlets.
Then again, I guess it's probably a fuel pump setup that's not common
to anyone else - the LyCont FI setups being accessory case driven..

The Holley with the leaning block looks better and better.  I'm not
_that_ interested in sustained inverted flight.  For naturally
aspirated, I think the Holley will be tough to beat.  Parts available
world-wide, any mechanic can figure out how it works, cheap rebuilds,
known tuneability.

I think the only way FI makes sense on the rotary is for forced
induction or for aerobatics (which opens a whole other set of
challenges (oil management)).  FI makes more sense on a regular
multi-cylinder piston engine because it offers relatively easy
balancing of fuel flows between the cylinders.  On a two rotor engine,
it should be relatively easy to get good fuel (and air) distribution
given that there are only two induction paths.

Matt,
Even easier for a single rotor.
