40NX RC Glow Engine with Muffler by Evolution Engines

40NX RC Glow Engine with Muffler by Evolution Engines Product Description Key Features More displacement, but same size and weight as .32-size engine Designed for use on 25- to 36-size aircraft Aftermarket high-performance muffler available for more power Low-speed SetRight™ needle valve Overview The NX series is designed to provide a unique combination of powerful performance, reliable engineering and remarkable ease of use. The .40NX is the same size and weight as our competitor’s .32-size glow engines, but packs more of a punch. Its displacement of .40 cu in provides sport models with plenty of get-up-and-go without adding weight. And since it’s an Evolution® engine, the .40NX has the innovative low-speed SetRight™ needle valve with a lever that makes easy adjustments and takes all the guesswork out of operation. Note: The 40NX was designed to bolt in extra horse power to most 25-32 sized aircraft. The 40NX will fly .40 size planes but with its smaller case size will not fit most .40 size engine mounts and with its light weight may require extra nose weight for proper CG balancing. Age Recommendation: Not for children under 14 years. This is not a toy.
