BetaFPV Four-Colour 1mm Shaft Propellers

These BetaFPV 40mm micro propellers feature a standard 1.0mm press-fit shaft, engineered for 75mm brushless whoops like the Meteor75 and Beta75X. Sold in a vibrant four-colour mix, these polycarbonate props offer reliable durability against indoor crashes while helping you maintain visual orientation in flight. They are available in two distinct geometries to precisely match your motor kv and frame weight requirements.

Key features

• Compatible with micro brushed and brushless motors featuring a 1.0mm shaft (including 0603, 0703, 0802, and 1102 series).
• 1635 3-blade variant provides lower amp draw, higher RPM efficiency, and longer flight times for lightweight 1S builds.
• 1636 4-blade variant increases cornering grip and low-end thrust for heavier whoops or indoor freestyle flying.
• Four-colour mix allows for easy customisation and instant line-of-sight tracking.

Press-fit installation requires no mounting screws. Ensure your motor shafts are exactly 1.0mm before ordering, as forcing these onto 1.5mm shafts will crack the central hub.
