O.S. technology comes to control-line engines!

Now control-line pilots can now take advantage of the power and affordability that have made “LA” the most popular letters in R/C.

• LA-S engines replace the carb with a venturi that keeps the engine running at a constant speed
• A remote-mounted needle valve—the most asked-for pilot option—is standard, rear-mounted for safety and added impact protection
• A nylon backplate mount and rachet spring help hold settings against changes caused by vibration
• An O-ring helps seal the needle from air and fuel leaks
• Heavy-duty webbing reinforces the one-piece crankcase in high-stress areas
• Other significant features include: bronze bushings for low-friction operation, a flat prop washer and longer crankshaft that provide more thread to engage, and a squared heat sink head and added fin area to increase cooling and enhance performance and longevity
• A bonus feature found on all LA-S engines: the fuel inlet and needle valve can be oriented either horizontally or vertically for added mounting flexibility.
