hmmmmm......mighty quiet. Nobody owns these engines?
Ok.....I can take a hint when it's time to use the search.
The OS BGX1 is a little more popular than the Supertigre 4500!!Which is like saying it's about as popular as a boat anchor. (Except a boat anchor is usually more reliable then a BGX, because a boat anchor is always designed to plant itself into the ground, while a plane with a BGX only does it when you least expect it)
There, lets see if that gets a response, now that I don't need any more help on the matter anyway. Figured it all out by myself did I!!
