Evolution 40NX RC Glow Engine with Muffler

This is the Evolution 40NX RC Glow Engine with Muffler.

Features

• More displacement, but same size and weight as .32-sized engine
• Designed for use on 25-36 sized 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.

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

Tech Notes

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.
