1147 11x4.7 Glass Fiber Nylon Propellers 1CW+1CCW

A matched pair of 1147 propellers — 11 inch diameter, 4.7 inch pitch — moulded in glass-fibre-reinforced nylon, with one clockwise and one counter-clockwise prop. The 11-inch size is a common fit for F450, S500 and similar DIY quadcopters and hexacopters on 2212-size motors.

Key features

• Glass-fibre nylon: stiffer than plain nylon for cleaner thrust, and more forgiving of knocks than brittle carbon blades.
• Two-blade, 4.7-inch pitch: a low-pitch profile suited to steady hover and efficient cruising on camera and trainer builds.
• Prop reducer rings included: two sets of reducers let the hub fit different motor shaft diameters.
• Grey finish with CW and CCW props in one pack — order two packs for a quadcopter, three for a hexacopter.

Specifications

• Size: 11 × 4.7 inch (approx. 28 × 12 cm)
• Blades: 2
• Material: glass-fibre nylon
• Colour: grey
• Rotation: 1 × CW, 1 × CCW
• In the box: 1 × CW propeller, 1 × CCW propeller, 2 sets of prop reducer rings

Fit the reducer ring that matches your motor shaft so the prop sits centred, and balance each prop before its first flight to keep vibration away from the flight controller.
