The Evolution® .91NX single-cylinder, 2-stroke glow engine is revolutionary for modelers who demand the most of their engines. This engine provides the performance of a .91-size engine in the case size of a .61-class engine, allowing you to put more power into smaller aircraft. The awesome power of the .91NX engines makes it possible to add a higher level of performance versatility to your .61-, .75- or .91-size airplanes, so that your 3D maneuvers have more punch and warbird strafing runs can reach speeds faster than you imagined possible.
Evolution glow engines are engineered for hands-on modelers who believe there's no replacement for displacement. Their awesome power-to-weight ratios and smooth operation make any flying experience, be it 3D, sport or scale, the best it can be. And they all benefit from ball bearing-supported crankshafts and the proven durability of ABC cylinder construction (aluminum cylinder with brass, chrome-plated liner).
Evolution 91NX Single Cylinder Glow Engine Features:- Smaller size and lighter weight than typical .91 displacement engines to deliver a higher power-to-weight ratio
- Fits the same mounting pattern as the .61NX engine
- Smooth operation that's easy to tune
- Dual ball-bearing support and ABC construction for performance and longer engine life
