It's new. I don't get why nobody is running them yet? When the beam mounted 20 came out, there was no hesitancy at all, and it's developed a pretty decent reputation since? This new engine is in basically the same case as it's weight and dimensions are the same as the 20cc engine's.
I think part of it might be that BP Hobby IS STILL showing the OLD radial mounted 26cc engine specs for the NEW engine? For pete's sake, what is it going to take them to publish the correct info?

This will be the next engine I buy. Took a temporary time out from gas to fly electric foamies (working on 3D), or I'd probably already have one. -Al
