Hey everyone. Little background before I ask my question. I have flown trainers, and I have flown some sport planes (I still have my U-Can-Do).

But it has been a few years and when I was in the hobby before, I never really took the time to make things right. I "rigged" a lot of things.

I dont want to do that this time. I still have my U-Can-Do but I want to get a trainer again just to get back into the flow of things. I still have my spektrum DX7 with servos that I plan to install in a Tower Hobbies Trainer. I flew one of my friend's, and they are a smooth trainer. I enjoyed flying it.


The question is about the engine.

I don't want to get a tower hobbies / GMS engine. They have given me nothing but trouble in the past. I need an engine that is pretty easy to setup (or comes with good documentation) since this is the first engine I am giong to do the "right way". I don't know much about the brands out there. There is OS, Thunder Tiger, and Super Tiger. I am leaning more towards OS just because they are the "tried and true" I guess you could say but if the others are just as good, please let me know for sure.

Also, is there a place that I could learn about engines online? For example, I dont know what the difference is between non-ringed and ringed.
