If this goes on a plane that is used a good bit the fuel savings will be very noticeable. The long flight times and reliability and lack of starting equipment will also be very nice. I love a plane that is paid for and costs very little each time I fly it from then on. Paying for glow fuel over and over gets so old. This motor should last a long time and this increases savings over the years.

I think that basing one's judgement to buy this engine based upon fuel savings (you did not mention this that I recall) is outright foolish. Yeah, I like the idea of a no clean-up model, but realistically, there has to be a novelty element to it in order to justify the expense of the engine. That novelty element was enough for me to buy. In years past, when money had to be targeted to accomplish a specific hobby task, this would not have happened/been true.
The mere fact that it is what it is, provides me with enough satisfaction. I have owned other BME products (44 & 50cc c.i.d. engines), so I know that Keith will keep me flying, should I need expert support.
On the other hand, there's nothing like being one of the first to own a new piece of technology. [8D]
