Hum ... ok. So I guess the Jab stinks....

Mmmm, better take that "feedback" with a grain of history:

The author had a Jabiru dealership in Australia at one time &
frequently extolled the virtues of the engine. When the rate of
exchange between the US & AD dollars got to an extreme, it became
possible to arbitrage the difference & pay Mr. Coates the Australian
retail price plus freight to the US for less than buying it at a US
dealer. This naturally caused a good deal of consternation among US
dealers & the end result was that Mr. Coates had his engine supply
shut off. Since then he's had nothing but negative things to say
about the engine. To my mind, this dichotomy in his opinions speaks
more of Mr. Coates than it does of Jabiru.

If you'd like some feedback from folks who are flying the engine,
check with Sonex builders on one of the Yahoo groups. I suggest:
http://groups.yahoo.com/group/sonexbuilders or
http://groups.yahoo.com/group/Light_...rcraft_Engines
These two groups are builder operated & you'll get honest open
opinions. Avoid any of the other Sonex groups are moderated by Sonex
LLC. They have a history of stomping pretty hard on anyone saying
anything that doesn't match their "policies".
