You know I would really like to purchase one of these new engines as I can see nothing but positives form the specs, pictures and your reports. The only thing keeping me and I suspect a number of other folks from pulling the trigger on the engine is a problem of Wild Hare's on creation. Your planes in the 50cc class have been so popular and have sold so well that many of us already have one, two or three 50cc airframes in our hangar. In my case I have two DA50 powered planes, a Brison 4.2 and the Sukhoi on a DA100. If our thumbs keep working well we have those airframes for a long time as they just don't wear out very often. If we do thunk one or just get tired of it, we probably look for the new offering from WH and in that case already have an engine on hand. I think if this engine was in the 80-85 cc range and you had a WH offering in the works -- well, I would already have both.

Having said all of that, I am still looking for an excuse to buy one as it is really hard to pass up such a good deal.
