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.
