Well, I have only been able to bench run the 55. I ran it for about 30 minutes and it was flawless. With the stock can muffler it turned a JXF 22x8 @ just shy of 7200, Idled very well at 1400 and transitioned quick and smooth. No need to run it any more on the bench. I recieved the shipment of engines at about 10:00am Mon., by noon #11 was on my Yak and ready to fly, it's been raining almost nonstop ever since.

I looked at and inspected every engine and made sure everything was in each engines box that was supposed to be there. I expected to see pretty and perfectly smooth castings but was a little surprised to notice cyinder castings, on the very lowest serial numbered engines, that were a little on the rough side in appearance only. The engines with higher serial numbers looked much better, one of the reasons I chose #11 to test. I'm all about function, and so far it does that well, I see every reason to think the new DL engines will perform as well or better than their predecessors. The 111's should be here today or tomorrow.
