I doubt Keith at BME will keel over and leave you without a motor, Steve Reinke also helps repair them at the shop as well. Bird, if you have this much doubt, why even bother with this motor? I would think with you being in Australia DA would be the logical choice since they have a service center there. I doubt you will have to send in your 115, but if you did it could take some time and $$, with the DA center there it would only take a week or so to get back in the air, my guess a month if you have to send the motor back here. As for a custom motor, the 115 is the only 100cc engine that is currently using the latest 6 port design, none of the other 100cc engines are. Keith has taken a look at cylinder technology (most of the technology we are currently using is decades old) and modified it for our use. I.E. the fins are thinner, they do not need to be as thick as the DA or 3W. I admire Keith for taking an idea and running with it, developing the idea and product of light and more power. There have been 100-200 or so BME 115s out there, if there were problems you would have heard about it and seen a bunch of them for sale. Its a great motor, but don't doubt it until you try it. If nothing else, leave all this conversation out of your buying process, and try one your self for an unbiased opinion, that will give you the best answer to your question about the 115. The phone number is on BMEs website, why not pick a time of the day where you can reach Keith and just ask him? If you had a question about a DA, wouldn't you call them? We aren't trying to sell you a 115, just giving our honest opinion on it. Trust me, if something is bad, I am the very first person to step up and say something about it.

PS, you can email [email protected] and [email protected] and they can give you some more unbiased info about the 115. Here is a link to a 115 on a WH sukhoi, its in different parts of the vid.
