hi sc is super custom ,made by a guy who used to build os engines and he uses the os moulds for these . i wouldnt pay for an os bb engine they are way too over priced in my opinion.im not sure where you would get the sc engines over there to be honest,they are very reasonable price wise and very strong engines too.id say get a 46 engine ,the thunder tiger engines are ok if thats what you can get easier.get an 11" prop for it or even a smaller 3 blade prop which as a freind says will get your engine lower and still give great power.ask where you buy the engine which one to get for best performance.good luck and happy xmas!!.
