T-Motor MF1806 18.4x6.6 Polymer Folding Propeller (Pair)

T-Motor's MF1806 is an 18.4-inch polymer folding propeller with a 6.6-inch pitch for long-endurance multirotors working at 1–1.8 kg of thrust per motor. The blades are moulded from polymer reinforced with carbon fibre and fold back along the arm for transport.

Key features

• Winglet tips weaken the tip vortex, and the downward winglet reduces radial centrifugal tension and blade deformation
• 0.25 mm trailing edge for lower airflow interference and a better lift-to-drag ratio
• Limit rubber ring protects the blade root from abrasion and absorbs shock; locknut-secured screws and two extra hole positions hold the blades firmly
• Heat-insulating, UV-shielding surface coating and heat-tolerant material for long flights in hot weather

T-Motor does not recommend its polymer props on coaxial frames, so use them on flat quad, hexa or octo layouts. Check each blade's rotation direction against your motor layout before fitting.
