New Rotax Engine - 912iS
Announcement in the mail this morning: http://www.avweb.com/avwebflash/news...1.html#gallery
Geez, my RV-12 is just like a computer - barely finished and getting obsolete already! First the avionics, now the engine!
The new engine looks like a winner, on paper at least. Fuel injection, electronic controls, etc., but based on a proven design. Only a matter of time before Van's switches over for the '12.

Sounds like they have fixed my major objection to the 912! Good for Rotax. Now if they can get it to run on regular grade ethanol infused fuel, or even 100LL without the ill effects it would be nicer yet..

I, too, would rather have the FI as opposed to doing the carbs even though I am used to balancing them. But, what will this be worth to us? Up to about $6K I would be in but after that?? I'm betting this engine will be close to $10K more.

External alternator needed
From the avweb write-up, it looks like the external alternator is needed to keep up with the FI power demands. As I recall, the standard external alternator is a serious wart on the front of the engine, so incorporating it into an RV-12 would require a bit of serious massaging.

It appears that the new 430 watt alternator will be located on the back of the engine where it is presently located, so no bump up front.

ROTAX - Pipistrel as 912 IS release customer
From the Rotax list in Matronics: http://www.matronics.com/listbrowse/...list/0000.html
"...Today is a significant milestone for both Pipistrel and ROTAX with the
release of the 912 IS engine, ROTAX have chosen Pipistrel as the 912 IS
release customer and the engine has been fitted and tested on the
award-winning Pipistrel Virus SW aircraft. Those that have flown the
aircraft report increased smoothness, faster throttle response, lower idle
and most importantly for the environment less fuel consumption for this
exciting new engine..."
