1045 Propellers Blue- 10x4.5 Inch CW+CCW for 450-size Drones

Specifications

• Diameter: 10.0 Inch (254mm)

• Pitch: 4.5 Inch

• Rotation: 1 x Clockwise (CW) + 1 x Counter-Clockwise (CCW)

• Material: High-Impact Reinforced Nylon

• Colour: Blue

• Centre Hole (Aperture): 6.0mm

• Adapter Rings: Included (Fits 3mm to 6mm shafts)

• Weight: ~12g per propeller

• Recommended Motors: 2212, 2213, 2216 (900KV - 1200KV)

Key Applications & Projects

• F450/F550 Quadcopters: The primary propeller choice for DJI-style multi-rotor frames.

• Aerial Photography: Low-noise, stable lift for capturing smooth video.

• Long Endurance Quads: Optimized for efficiency during steady hovering and slow-speed cruising.

Unlock New Capabilities (Project Evolution)

• Feature Upgrade: Switching to a 4.5 pitch from lower pitch props offers a better balance of torque and battery life for standard 3S or 4S LiPo setups.

• Effort Level: Beginner. Includes a full set of adapter rings to ensure a perfect fit on motor shafts ranging from 3mm up to 6mm.

Package Includes:

• 1 x 1045 Clockwise (CW) Propeller (Blue)

• 1 x 1045 Counter-Clockwise (CCW) Propeller (Blue)

• 2 x Sets of Adapter Rings (Varying diameters to fit different motor shafts)

FREQUENTLY ASKED QUESTIONS (FAQ)

1. What does "1045" stand for? "10" is the diameter in inches, and "45" is the 4.5-inch pitch (distance traveled in one revolution).

2. Will these fit my 1000KV brushless motor? Yes, 1000KV on 3S is a standard and reliable setup for 10-inch props.

3. How do I tell CW from CCW? The CW prop rotates clockwise (viewed from top) to push air down; usually marked as "1045" and "1045R".

4. Are these durable for crashes? Reinforced nylon is very tough and will often bend rather than shatter upon light impact.

5. What if my motor shaft is 5mm? Simply use the included 5mm adapter ring to ensure the prop is perfectly centered.

6. Are they balanced? They are factory-molded for balance, but we always recommend a final check on a manual balancer for professional video work.

7. Do they reduce flight noise? The aerodynamic profile is designed to minimize blade "flutter," leading to quieter operation.

8. Can I use these on a DJI Phantom? No, Phantoms usually require proprietary "self-tightening" hubs.

9. What is the maximum recommended current? This depends on your motor; 1045 props typically draw 12A–18A at full throttle on 2212 motors.

10. How many propellers are in the pack? You get 1 pair (2 propellers total: one CW and one CCW).

11. Can I paint them? While possible, it's not recommended as it will throw off the dynamic balance of the blade.

12. What happens if I install them backward? Your drone will push air up and fail to lift. The curved side with markings should face the sky.

13. Can I use these for FPV racing? They are "Slow Fly" props; racers generally prefer stiffer, higher-pitch 5-inch or 6-inch props.

14. What is the center hole size? It is a standard 6mm aperture.

15. Are these suitable for 4S batteries? Yes, but ensure your motor can handle the heat of 4S with a 10-inch load.

16. Can I ream the center hole to 8mm? No, the hub structure is optimized for 6mm; reaming it larger may weaken the prop.

17. Are the adapter rings plastic? Yes, they are made of high-density black plastic.

18. Will these help with "jello" in video? Yes, by providing a more stable lift profile compared to thinner blades.

19. What is the hub thickness? Approximately 9.5mm to 10mm.

20. Can I use them for a pusher plane? Yes, just ensure the leading edge is facing the direction of rotation.
