The engine business is just a hobby for guys like Dub Jett. They make them because they have the machinery to do so. If the market dries up any further, I wouldn't be surprised if even he throws in the towel. I certainly don't expect any major development...there's just no way to break even on a few hundred engines.
If guys like Jett come out with something new, it is basically out of love for the hobby.
I broke in an ASP .36 yesterday, 8x6-8x7 props, mousse can muffler, FAI 80/20 fuel: 18K+ rpm. It runs and throttles fine, but it is just not as sweet as a Webra. You can tell the engine is maxed out in it's stock trim. Behaves fine up to about 14K, then it starts to vibrate. It is not balanced for higher speeds. A good sport engine, if you run it on a 10x6 or 10x7, but other than that it is just a run of the mill chinese cheap engine. So basically, I'm disappointed even before the engine gets flown.
I'd gladly pay two times as much for an engine that is 10% better...
