Sorry, all the bragging in the world won't justify that price for me. Personally I'll just wait for more of them to get out, hopefully a lower price will reflect that. Also, its a little too cold in the doghouse right now...

As for the ys 63, having own one for 2 years now, I'm hardly an expert, but I do not have any problems with mine. I can tell you that of the guys I know who had problems with ys engines, most of them were running 15% syn/cas blended fuel (I only run 30% heli). I do know 2 guys who had their tuning problems disappear when they went to 20% syn fuel.
