As of right now I am the only importer trying to set-up support for this engine that I know of, I have worked on the sole import also. I have the engines in stock for delivery and I am setting up a new location for when the new line of arf airplanes arrive. We have had great results so far and look foward to getting more of these engines out to the flying fields. All the engines have started easy and run great out of the box, one gentlemen has tested it with up to a 24-8 prop and still got 6400 RPMs out of it. 7000rpms on a 22-10 with stock muffler. Transitions are good, the carb is a check valve model so it won't draw from the chamber in the idle position. This will help with a good solid idle setting and provide for a smoother transition in the mid-range.
We like em and are flying them now, we will have a few of them flying in IMAC this summer and I have high interest from the 3-D guys due to the low cost and availability.
Thanks
Scott
