3K Carbon Fiber 1555 Propeller Pair 15x5.5 (CW+CCW)

A matched pair of 15 × 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 1555 stands for a 15-inch diameter and a 5.5-inch pitch, a low-pitch profile that trades top speed for efficient hover and lifting.

Key features

• 3K carbon fibre weave (3,000 filaments per tow) with high structural stiffness, so the blades hold their shape at large diameters
• Less flex and vibration than plastic props of the same size, which makes tuning easier and keeps camera or sensor payloads steadier
• Two-blade, fixed-pitch design with a carbon weave finish
• CW + CCW pair, so one pack covers two opposite-rotation motors

Check the centre-hole size against your motor's prop adapter and confirm your frame's motor spacing clears 15-inch blades, then balance each prop before its first flight. A quadcopter needs two pairs, a hexacopter three and an octocopter four.
