I think this is a very good topic. I'm one of those who hate spending alot of money on things that fail. I can understand your frustration and throwing out the darn engine because I've done thing similar in the past. Knowing what I know now I think you should pull the engine out of the trash, send it back and call them up and explain what keeps happening. I'd be nice but persistent about it and demand that they fix the problem or get your money back and buy a engine that is a little more reliable. JMHO
I got a question for you guys. Is it possible to cause that kind of damage, if I were to swing a prop out side of the engine manufacture recommendations, as I was braking the motor in?

I never tossed out an engine. Kangke is very good at standing behind what they sell. I will be calling and getting some information from the owner monday. This engine is under warenty. Even when I kill an engine in a crash there are a lot of screws and parts I use when I'm rebuilding other engines people give me.
I have seen several engines break when I was pitting for a race tems. The cause is simple. An engine has a working RPM range and sometimes the manufacture tends to go a bit too high with the RPMs. They tend to run very small props with different pitches to get those high RPMs then post them. Doesn't always work in the real world. Racers tend to go for as many RPMs they can get and use small props with a high pitch and to get every rev they can get so rods and cranks let go quite often.
In my case I was just flying the basic pattern and pulling a lot less RPMs then the engine calls for so it was a shock to me. The SKs are a low RPM high torque engine anyway and not used for any type of racing.
There could also be a problem in the manufacture. My other SK engines were all great, maybe they are being made in a different plant? I will find out tomorrow. It's not a big deal at the moment, it was just a first for me. A few weeks before I had my first mid air, I seem to be going through a first time faze or something?
I also don't run two strokes very often any longer so i go the cheap route. These engines are great and only $100.00 with a muffler. If there is a problem I will just use another four stroke or spend the money and get another OS two stroke. I have just had great luck with the SKs and like them better then the OS. Some may say you get what you pay for and I'm one of them. I tried SK and like them, if they are having a problem I won't bother with them anymore.
I'm also one of the suckers that bought the MDS line some years back. There was total junk!!!
