GB one of our locals tried a new SK 1.08 about two years ago During the first runs the connecting rod and or the rod journal broke. The airplane never got to fly and the gentleman doing the brake in was no beginer and a well versed engine man.
I cannot give you the exact specs but the engine was immediately returned and it was replaced without question. The problem was the replacement engine did the exact same thing. It was a complete writeoff and he just threw it away.

I have had a couple of the .91s and had great luck with them. I do have one that I tried to plant on it's nose that still runs but it over heats in about 15 seconds. Before the crash it was perfect. I wasn't over reving either, just doing a turn around and rolling on the throttle. I had it set at 9200 on the ground so even if I was on it the engine shouldn't have broken. I'm going to phone Kangke Monday and tell him about it and make sure opening it up doesn't destroy my waerinty.
I was more surprised about the oil clog I had. I have seen one YS do something like that years ago but it took a lot longer to clog. Maybe it doesn't like the Klotz?? It was sure thick!!
I will let you know if I find out if SK is having a rod problem or not. Sounds like something may be going on.
