The reinforced hub, 7.5 mm thick, withstands high loads and reduces vibration. Recommended for motors 2506–2810. Choose high-quality consumables for dynamic flights.
High strength composite material. Glass-filled polyamide with armamide provides rigidity, wear resistance and impact strength.
Three-blade design. Creates smooth traction, improves stability during hovering and sharp maneuvers.
Light weight 10 g. Minimizes rotor inertia, improving throttle response and extending flight time.
Reinforced hub 7.5 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 8×4×3 propellers convert engine rotation into lift and thrust. The 8" (203mm) diameter provides the optimal balance between maneuverability and payload capacity for medium to heavy 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.
High-strength composite material with the addition of armamide maintains the geometry of the blades at high speeds and is resistant to impact and abrasion. 5mm mounting hole fits most 25-28 series motors. The reinforced 7.5 mm thick hub reduces vibration and the risk of destruction during sudden maneuvers and hard landings.
Includes 2 right (CW) and 2 left (CCW) screws for torque compensation. The weight of one propeller is only 10 grams, which reduces inertia and improves dynamics.
KB-Spectrum 8" blades are ideal for 7-8" racing drones, freestyle copters and light cargo platforms. Thanks to their low weight and reinforced hub, they provide excellent dynamics and durability.
