The highly acclaimed SC range encompasses aircraft, marine and helicopter engines in a vast range of sizes from 2cc up to 64cc multi-cylinder radial engines. Ballraced crankshafts and ABC piston/liners All SC engines have crankshafts supported by dual ball bearings which run and run when compared with the cheaper plain bush bearings found in so many sports engines today. The all-important piston and liner is ABC in nearly all SC 2-strokes to give the best fit and performance for model engines. ABC setups provide competition levels of power and a brilliant resistance to seizure if the mixture control is wrong. The perfect answer for sport flying. CNC machining Exquisitely machined components feature in so many engines throughout the range – which is why SC engines look as good on the inside as they do on the outside.
