Product overview
The Gemfan LR 7035 is a propeller component for 7-inch FPV drone builds, supplied in packs containing both rotation directions. Its two-blade architecture and 3.5-inch pitch target a balance of flight efficiency and responsive handling for endurance-focused applications. Intended roles include medium-to-long-range cruising, light freestyle and general-purpose flying, with the pitch also designed to support smooth power delivery for cruising and cinematic applications. Each polycarbonate propeller weighs approximately 6.5 g and measures approximately 178.6 mm, or 7.0 inches, in diameter.
Motor integration uses a 5 mm shaft hole designated M5, with compatibility specified for 22xx-23xx series motors. Application examples include 2207 and 2306 motors. The physical dimensions also include a 7.0 mm hub thickness and a maximum blade width of 17.5 mm, defining the propeller’s mounting and blade envelope. Each pack supplies two clockwise and two counterclockwise propellers. The intended integration scope is 7-inch FPV builds using this mounting interface and motor series, particularly applications prioritizing flight duration and stable control.
