uxcell 9x4.5 Inch RC Propeller Set (CW/CCW) - 3-Blade Nylon with Adapter Rings for Multi-Rotor Aircraft

This uxcell propeller set includes one clockwise (CW) and one counterclockwise (CCW) 9x4.5 inch nylon propeller designed for multi-rotor RC aircraft. Each propeller has three blades and comes with two hole adapters to fit either 6mm or 9mm motor shafts. The set is a direct replacement for many RC planes and multirotors, offering a lightweight nylon build that balances strength and weight for efficient flight.

Dimensions and fit details

Each propeller measures 9 inches in diameter with a 4.5-inch pitch. The 3-vane design provides a distinct look and performance characteristics compared to standard 2-blade props. Shaft compatibility is flexible: the included adapters let you mount them on motors with either a 6mm (small) or 9mm (large) shaft. The total weight per set is about 2.08 ounces, and the package dimensions are 7.95 x 7.83 x 0.63 inches.

What you get in the pack

• 1 x CW (clockwise) propeller
• 1 x CCW (counterclockwise) propeller
• 2 x hole adapters (for 6mm and 9mm shafts)

All parts are made from black nylon, a durable plastic commonly used in RC propellers for its impact resistance and light weight. The adapters help you switch between common shaft sizes without additional hardware.

Will these propellers work with your RC aircraft?

These propellers are intended for multi-rotor models and some RC airplanes that use a standard 9x4.5 inch prop size. Always verify that the diameter and pitch match your motor and frame specifications. The set includes both CW and CCW rotation, so they can be used on quadcopters and other multirotor builds that require opposite rotation on diagonal arms. For single-engine planes, you would use only the appropriate rotation direction.

Common questions about the uxcell 9045 propellers

How do I know if the 6mm or 9mm adapter is correct?

Measure your motor shaft diameter. If it's 6mm, use the smaller hole adapter; if 9mm, use the larger one. The adapters fit snugly over the shaft and into the propeller center hole.

Are these propellers balanced out of the box?

The manufacturer does not specify balancing; many users find them sufficiently balanced for general flying, but you may want to check and balance them for precision performance.

Can I use these on a 3D airplane or a heavy-lift drone?

These are designed for general multi-rotor use. For high-stress applications, you might need a stronger material like carbon fiber. The nylon props are best for standard recreational flying.

Technical specifications at a glance

This propeller set offers a straightforward way to replace or upgrade your RC multirotor or plane. With two rotation directions and shaft adapters included, it covers common motor setups. Always double-check your existing prop size before ordering.
