آرڈر کے لیے سائن ان کریں →Provide excellent dynamics and reliability for 7" quadcopters and freestyle drones. The three-blade 7x4x3 (7 inch, 4.0 pitch) propellers are made from high-strength glass-filled polyamide with Armamid fiber reinforcement. The reinforced 6 mm thick hub can withstand high loads and reduce vibrations. Choose high-quality consumables for dynamic flights.
High-strength composite with armamid. Rigidity, wear resistance and toughness for intense flights.
Three-blade design. Smooth traction, improved stability during hovering and sharp maneuvers.
Light weight 10 g. Minimizes rotor inertia, improving responsiveness and flight time.
Reinforced hub 6 mm. Reduces vibration and prevents damage during hard landings.
Set 4 pcs (2CW+2CCW). Complete X-frame kit, ready to install.
Three-bladed KB-Spectrum 7×4×3 propellers convert engine rotation into lift and thrust. The 7" (177.8mm) diameter provides the optimal balance between maneuverability and payload capacity for mid-sized FPV drones. The 4.0" pitch creates good speed with moderate current consumption. Three blades are more effective than two blades in hover mode, providing a more stable flight and better responsiveness.
A high-strength composite with the addition of armamide maintains the geometry of the blades at high speeds and is resistant to impacts and abrasion. The 5mm mounting hole fits most 22-25 series motors. The reinforced 6 mm thick hub reduces vibration and the risk of destruction during sudden maneuvers. Includes 2 right (CW) and 2 left (CCW) screws for torque compensation. The weight of one screw is only 10 grams.
KB-Spectrum 7" blades are ideal for 7" racing drones, freestyle copters and light cargo platforms. Thanks to their low weight and reinforced hub, they provide excellent dynamics and durability.
