Gemfan LR7035 Bi-Blade 7" Propeller (Set of 4 — 2CW+2CCW)

The Gemfan LR7035 is an ultralight bi-blade propeller engineered specifically for maximum efficiency on lightweight 7-inch long-range builds. Weighing just 4.2g per prop, its shallow profile minimises current draw during extended cruising, making it an excellent match for endurance flights and lithium-ion (Li-ion) battery setups. This specific variant features a 2mm centre hole to fit small-stator, lightweight motors.
