Gemfan 8038 Carbon Fiber Nylon Propellers - 8x3.8 Inch CW+CCW Pair for Multirotor

Specifications

• Diameter: 8.0 Inch (203.2mm)

• Pitch: 3.8 Inch

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

• Material: Carbon Fiber Reinforced Nylon (Matte Black)

• Centre Hole Diameter: 6.0mm (Standard universal hub)

• Hub Thickness: 9.0mm

• Weight: ~15.3g per pair

• Recommended Motors: 900KV - 1200KV (e.g., A2212 / 2216 series)

Key Applications & Projects

• Aerial Photography: Low-noise, stable lift for capturing cinematic footage with F450-class drones.

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

• Fixed-Wing Slow Flyers: High-torque propulsion for park flyers and indoor model airplanes.

Unlock New Capabilities (Project Evolution)

• Feature Upgrade: The carbon nylon material inherits the high hardness of carbon fiber while retaining the impact resistance of nylon, making them far more durable in minor "tip-strikes" compared to pure carbon fiber props.

• Effort Level: Beginner. Includes a full set of adapter rings to fit almost any motor shaft (3mm to 8mm).

Package Includes:

• 1 x Gemfan 8038 Clockwise (CW) Propeller

• 1 x Gemfan 8038 Counter-Clockwise (CCW) Propeller

• 2 x Sets of Adapter Rings (3mm, 3.17mm, 4mm, 5mm, 6mm, and 8mm)

FREQUENTLY ASKED QUESTIONS (FAQ)

1. What does "8038" stand for? The "80" is the 8.0-inch diameter, and the "38" is the 3.8-inch pitch (the distance it travels in one revolution).

2. Are these better than 8045 props? The 8038 has a lower pitch, meaning it is more stable and efficient for slow flying, whereas the 8045 offers more top speed.

3. Will these fit my 1000KV brushless motor? Yes, this is the standard size for 2212/1000KV motors used in 450-size frames.

4. Are they safe for 4S LiPo batteries? Yes, as long as your motor/ESC combo is rated for 4S with an 8-inch prop.

5. Do they come in different colors? Carbon Nylon props are typically matte black due to the carbon fiber content.

6. How do I tell CW from CCW? CW propellers push air down when rotating clockwise (viewed from top); CCW props push air down when rotating counter-clockwise.

7. What if my motor shaft is 5mm? Use the included 5mm adapter ring to ensure the prop is perfectly centered on the shaft.

8. Can I use these on a Parrot AR Drone? Yes, these are a popular high-performance upgrade for the Parrot AR 1.0/2.0.

9. Are they balanced? They are factory-balanced, though a quick check on a manual prop balancer is always recommended for perfection.

10. Do they produce less noise? Yes, the stiffness and aerodynamic profile significantly reduce "flutter" and noise.

11. Can I use them for FPV racing? They work, but racers usually prefer higher pitch props (like 5045 or 8045) for faster bursts.

12. Are they magnetic? No, the carbon-nylon composite is non-magnetic.

13. How many pairs are in one pack? This product includes 1 pair (2 propellers total).

14. What is the center bore size? The raw bore is 6.0mm, adjustable via the included rings.

15. Can I ream the center hole larger? Yes, they can be reamed to 8mm or 1/4" if needed.

16. Are they rigid? Yes, they are three times stronger than standard nylon paddles.

17. What happens if they hit a branch? They are impact-resistant but may chip or snap; carbon-nylon is less flexible than pure nylon.

18. Do these help with "jello" in video? Yes, by reducing vibrations from propeller flex.

19. What is the center thickness? It is approximately 9.0mm.

20. Can I use them for a pusher configuration? Yes, just ensure the propeller orientation is correct relative to the motor direction.
