4-Pack Folding Propellers For RC Airplanes - 6x3 To 10x8 Sizes, Fits 3.17mm To 6mm Spinners (Choose Your Size)

These folding propellers are perfect for RC gliders, sailplanes, or any electric plane where you want the prop to fold back when the motor stops. They reduce drag in flight, which can help with glide performance.

You get 4 propellers in one of the listed size sets (like 6x3, where 6 is the diameter in inches and 3 is the pitch). The root is 8mm wide and fits spinners with shaft diameters of 3.17mm, 4mm, 5mm, or 6mm. Just make sure you pick the size that matches your motor's kV and your plane's needs.

They're lightweight and designed to be durable. A great upgrade if you're building or repairing a foamie or balsa glider. Always balance your props before use for the smoothest operation.
