3K Carbon Fiber 1155 Propeller Pair 11x5.5 (CW+CCW)

A matched pair of 11 × 5.5 inch propellers in 3K carbon fibre, one clockwise and one counter-clockwise, for large multirotors running low-KV motors. Size code 1155 stands for an 11-inch diameter and a 5.5-inch pitch, a low-pitch profile suited to efficient hover and steady lifting rather than outright speed.

Key features

• 3K carbon fibre weave (3,000 filaments per tow) for stiff, light blades that hold their shape under load
• Less flex and vibration than plastic props of the same size, which makes tuning easier and keeps camera footage 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 before fitting, and balance each prop before its first flight. A quadcopter needs two pairs and a hexacopter three; carbon edges are sharp, so keep hands clear when arming.
