They will never in a million years get the FAA to certify an EFI
system. Lycoming has been trying for eight or ten years so far. If
Lycoming can't do it Mistral won't be able to do it. They should
stick and aircraft carb on it.

Rockwell Collins has a EFI unit that *is* certified and is available
on a Rotax. I'm involved with another program and we have talked
with R/C about a system for a 6 cyl. aircraft engine. Their stuff is
well done but a little pricey for the homebuild crowd.

Is that for the Predator Rotax?

Paul Lamar

I don't know if Predator uses the injected version. If they do, they
must be new and/or converted airframes.

Here's a link to a commercial use:

That is Light Sport. A whole different engine rule system.


Paul Lamar

In a phone meeting with Rockwell Collins this morning, I inquired
about
the "level" of their certification.  According to them, the Rotax
package
if "fully" certified and can be used in any airframe either new
or with a
STC.  Rotax also offers an uncertified version for LSA, etc.

There is no "certification" required for LSA in this area.

Gary Knutson

Maybe Rockwell knows something about the FAA Mistral and Lycoming
don't :)
It may have  something to do with the source code.
As I recall they have to verify the source code and there are no
bugs that might
cause the engine to stop.

Paul Lamar

No, they should just use an aircraft fuel injection system on it, like the
one that is on certified Lycomings.  When I get around to setting up the
helicopter engine I plan on doing, I'm going to use a system from these
guys:

It may not be cheap, but it works.
