Wow, thanks for the replies. I have heard about some of the problems with GMS engines. That is why I was looking into the Evolution 100. Another guy at my field has one with an Evolution and it has excellent performance. THe OS would be a good choice also , but the price is a bit steep at $305 CDN. Young- Rcpilot seeing as you are from Canada, where do you get your stuff and is it cheaper than hobby wholesale.

Thanks again.
