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.

Age Recommendation: Not for children under 14 years. This is not a toy.

Technical Notes

The 40NX was designed to bolt in extra horsepower to most 25- to 32-size 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.
