Brass Heavy Spinner Nut – 1/4"-28 (Great Planes) | High-Mass RC Prop Spinner Nut

The Great Planes Brass Heavy Spinner Nut – 1/4"-28 is a strong, high-quality propeller nut designed to help your glow engine run smoother and more reliably. Made from solid brass, this nut adds extra weight to the front of your engine. That added mass works like a small flywheel, helping steady the idle, smooth out throttle changes, and reduce engine vibration—especially on single-cylinder glow engines.

The 1/4"-28 thread fits many common glow engines used in trainers, sport planes, scale models, and aerobatic aircraft. Brass is very durable, so this spinner nut holds tight through many flights and propeller changes without wearing out.

The rounded, polished shape gives your aircraft a clean, professional look and also makes hand-starting safer and more comfortable. Many RC pilots use heavy brass spinner nuts to improve low-RPM performance without needing to adjust the carburetor or swap other engine parts.

Whether you're tuning a new engine, upgrading an older model, or looking for smoother and more consistent flights, the Brass Heavy Spinner Nut is a simple, effective improvement.

• Solid polished brass
