Hey, I know this engine is very expensive, but besides the cost who's going to stop you. I know there are lots of technical guys out there... Maybe we can melt those chinagurls into these things... I hope the chinese will come up with a version of this engine. Maybe we can write to those Chinese manufacturers and specify to make one of these. They're already producing some very good R/C engines, so why not a mini V6 or mini V8 engine. I think if there's a market, they'll manufacture these babies.
