Gemfan Floppy Proppy 5135 Foldable Tri-Blade 5" Propeller (4-Pack — 2CW+2CCW)

The Gemfan Floppy Proppy F5135 is a 5.1-inch foldable tri-blade propeller designed for 5-inch freestyle and long-range FPV quads where compact transport is essential. The folding blade design allows the propellers to swing back along the frame arms during transit, eliminating the need to remove props before packing your drone into a bag or backpack.

Key features

• Foldable tri-blade structure that collapses backward on impact and during storage to help prevent blade snaps
• 3.5-inch pitch provides a balanced mix of responsive thrust and efficiency for freestyle and cruising flight
• Mated to a CNC-machined aluminium centre hub with standard M5 motor shaft mounting and POPO system compatibility
• Moulded from impact-resistant polycarbonate (PC) for durability under high-RPM flight loads
• Optimised for 2206 to 2407 brushless stator sizes across 4S to 6S power setups
