As I understand it, over 200 engines have been sold, which is quite a lot. Max apparently loves the UL260i, which is getting a foothold in Europe with numerous planes flying. In the Bantam, it appears too make for a nice installation as does the Jabiru. My research has shown that there is considerable doubt amongst people who haven't seen the engine or flown it, which is natural. The adherents are those who have as well as those who have visited the factory. Apparently, the engine is extremely well made. I admit to having no direct knowledge of it, however.
I hope to visit the NZ factory in December and possibly will bring a Bantam over to Tasmania next year. While Micro Aviation's NZ website doesn't give much information, there is more on the Micro Aviation SA site. There are several other Bantam videos on YouTube, just search micro aviation SA, and Bantam. IMO, there should be a nice market for Bantams in Australia and it's a bit surprising it never took off here (if you'll forgive the pun) . Or perhaps I should say "yet"...
