I checked out the reviews on this site; it got really positive reviews, but only 7 people have submitted. I did a search for the engine on google, and didn't come up with a lot of vendors, which tells me it might be harder to find parts.

I think it's important to note that the top end rpm has a much lower rating than the other engines in this size/price range; sounds like you would need to use a larger prop to achieve the same air speed as the competition, but the .50 should be able to do that ok.

I value buying an engine from a hobby shop that I know will stand behind their product, especially if it's a company you're not familiar with.

But what do I know[8D]
