I've been looking for the same engine for years. There is no such animal.
Finding a 4 stroke with the same power and weight of the Rotax 447 would be the answer to reviving legal 103 airplanes. -- Mitchell Wing http://www.mitchellwing.com -- Have a good day and stay out of the trees! See ya on Sport Aircraft group http://groups.yahoo.com/group/Sport_Aircraft/ "Richard Riley" wrote ... I'm looking for an engine that may not exist. If anyone has a notion of what it might be, I'd be grateful. It's for a 103 legal ultralight. 60 lbs or so all up, including re-drive and cooling 35-40 hp. 4 stroke. More reliable than a 2 stroke Rotax Any ideas?

I have no specs, but a year or so ago I visited a guy who was building
a plane with a BMW opposed twin motorcycle engine. He had found a new or nearly new one somewhere. I have moved and lost track of him, but this was his third plane (second of his own design), and he had previously used Rotaxs. David Johnson

Not sure if this was mentioned earlier in this rather old thread, but
these guys have a pretty interesting solution. http://www.ecofly.de/english.htm
