Product description not too many years ago the joy that we r/c club flyers experienced in owning and operating two-stroke glow engines was taken away. Whether we liked it or not, we were driven to use exclusively electric or petrol power systems in our models. Not anymore. Sc two-strokes are back, better than ever and poised to indulge your passion for engineering and your desire to enjoy all forms of r/c propulsion. Enjoyed by owners due to their easy starting, endearing handling, smooth running and clean throttling, an sc two-stroke engine will enrich your r/c experience no end. That's a fact. Boasting a beautifully cast matt-finished crankcase with twin phenolic bearings, a sturdy, single billet crankshaft and twin needle carb with, in the most part, rear-mounted main mixture adjustment, these are engines that look good and run beautifully. Fit a smooth-running sc two-stroke to your latest build and you'll not only be adding variety to your r/c life, you'll be adding guaranteed satisfaction and a hint of nostalgia.
