Hello Pilots:

There is an AVID on Barnstormers, had been sitting there for a while, the price seems to be right for Jabiru/Speedwing, any idea what could be NOT right? Appreciate for any advice from the experienced pilots!

Far be it for me to act like an expert on this subject, except that I am sure that you will find most of the posts by the owners/pilots/builders of the Avids to be negative on this engine.

The Jab without redrive requires a very short prop - therefore, you lose the ability for short takeoffs.

#2. There have been bad reports on the Jab engine, concerning valve problems.

Other than that, I have no helpful info.

Actually I have a friend with a Mark IV heavy hauler with an 80 hp Jabiru. Other than the continuing issued with keeping the CHTs down, it is a fine running motor that does a reasonable job (equatable to a 582) for that plane.

There is currently a speedwing, 582 powered IV in another buddies hangar to which he (CFI) is giving dual to the owner of the plane for checkout. This plane, with wing extensions, is almost unflyable. It barely climbs (300-400 fpm in cool fall weather!) with two on board with minimal fuel. So, taking that plane and putting the lower thrust Jab motor on it would be horrible.

One man's opinion.

Never heard of anyone complaining about 582 performance. What is his problem? Prop? Speedwing? Reduction ratio?

Site Sucks now.
