6x4 or 6040 The propeller is 6 inches in diameter with a 4-inch pitch. "6040" is simply another way of writing 6×4. Is a high-quality Nylon Propellers for RC Airplanes designed for KV2200-2450 brushless motors. Ideal for RC airplane enthusiasts seeking durable, balanced performance.
E:Electric propeller, designed for electric brushless motors rather than glow or gas engines.
R:Reverse-pitch (also called a pusher) version of the propeller. It produces thrust in the opposite direction when spinning the opposite way.
CW:Clockwise rotation.
CCW:Counter-clockwise rotation.
2-blade The propeller has two blades, making it lighter and generally more efficient than 3-blade props.
Nylon Made from durable nylon plastic, commonly used for RC aircraft propellers.
KV2200–2450 motor Intended for brushless motors with a KV rating between 2200 and 2450, where KV means RPM per volt (for example, a 2200 KV motor spins about 22,200 RPM on 10 V with no load).
Size: 6x4R=CCW Prop
Color: Gray
Weight: 3.5g/pc
Hole diamater: 6mm
Length: 15.24cm
This lets you choose the correct prop depending on whether your motor rotates clockwise (CW) or counter-clockwise (CCW). On multirotors, both types are used together. On an RC airplane, you normally use only the propeller that matches your motor's rotation.
Typical applications
These propellers are suitable for:
RC airplanes
Flying wings
Some FPV aircraft
Small multirotors using 2200–2450 KV brushless motors (depending on the motor and battery setup)
