3K Carbon Fiber 1655 Propeller Pair 16x5.5 (CW+CCW)

A matched pair of 16 × 5.5 inch propellers in 3K carbon fibre, one clockwise and one counter-clockwise, for heavy-lift and industrial multirotors running low-KV motors. Size code 1655 stands for a 16-inch diameter and a 5.5-inch pitch, and each prop mounts directly to the motor through its centre and side holes.

Key features

• 3K carbon fibre weave (3,000 filaments per tow) for stiff, light blades that hold their shape at a 16-inch span
• Direct motor mounting through a 4 mm centre hole and 3 mm side holes
• Less flex and vibration than plastic props of the same size, which makes tuning easier and keeps camera or sensor payloads steadier
• CW + CCW pair, so one pack covers two opposite-rotation motors

Confirm your motor's shaft and bolt pattern match the 4 mm centre hole and 3 mm side holes, and that your frame's motor spacing clears 16-inch blades, before fitting. Balance each prop before its first flight; a quadcopter needs two pairs and a hexacopter three.
