Product Description

Enjoyed by owners due to their attractive price, easy starting, endearing handling, smooth running and clean throttling, SC four-stroke engines began winning friends from the day they first appeared. Boasting decades of stirling service to the R/C community, SC’s exquisitely engineered, jewel-like, single-cylinder overhead valve four-strokes quickly become firm favourites with sport and scale club pilots the world over and now they’re back, better than ever. Boasting a twin bearing camshaft, a twin bearing, single billet crankshaft, eye-catching chrome-plated pushrod tubes and an investment cast crankcase, matt finished to a very high standard, these are engines that not only look good but run beautifully, too. Truth is, SC four-strokes are a pleasure to own, a pleasure to operate and, crucially, a pleasure to hear.

Fit a real engine to your latest build and you’ll not only be adding authenticity, you’ll be adding a touch of class with a hint of nostalgia.
