1238 12x3.8 ABS Propellers (1CW+1CCW)

A pair of 12 × 3.8-inch two-blade ABS propellers, one clockwise and one counter-clockwise, for 12-inch multirotor builds running low-KV motors. The low 3.8-inch pitch favours efficient hover and smooth lift over top speed, which suits camera, mapping and long-endurance airframes.

Key features

• 12-inch diameter, 3.8-inch pitch, two blades
• 1 CW + 1 CCW pair; a quadcopter needs two pairs
• Light ABS plastic construction
• Angled 15° tips intended to reduce tip vortices
• Set of plastic shaft reducers included (3, 4, 5 and 6 mm)

Specifications

• Diameter: 12 in (305 mm)
• Pitch: 3.8 in
• Blades: 2
• Material: ABS
• Colour: Black
• Weight: 34 g
• Pack: 1 CW + 1 CCW, with reducers

On a quadcopter, adjacent motors need to sit more than 305 mm apart, centre to centre, to clear 12-inch blades. For heavier payloads where blade flex shows up as vibration, the carbon nylon 1238 is the stiffer option.
