The one item I have heard from reading feedback about the Evolution engines, is that without their tuned pipe: http://www.horizonhobby.com/Products...D=EVO30984268E they really don't hold their own in the performance department. And WITH the tuned pipe and its additional weight, along with the money invested, it narrows the margin between any idea of saving weight or getting more power out of a smaller, lighter package as compared to the Zenoah or other similar options available, making it a not-so-attractive option any longer.

If you would like to save some weight compared to the Zenoah g38, and still have the great performance and longevity qualities, look into the Brillelli 36GT. It is a VERY reasonable value for what you get, and Scott is a great guy to work with.
