FREQUENTLY ASKED QUESTIONS (FAQ)

1. What does "1038" stand for? "10" is the 10-inch diameter; "38" is the 3.8-inch pitch.

2. Are these original DJI propellers? No, they are high-performance Gemfan alternatives designed to the same specifications for a perfect fit.

3. Will these fit my 2212 920KV motors? Yes, this is the most common motor pairing for 1038 propellers.

4. Are they better than 1045 props? 1038 props offer more stability and better efficiency for hovering, while 1045 props offer slightly more top speed.

5. How do I tell CW from CCW? The CW prop rotates clockwise (from top) to push air down; usually marked as "1038" and "1038R."

6. Can I use these with 4S batteries? Yes, provided your motor and ESC are rated for 4S with 10-inch propellers.

7. Do they come with adapter rings? Yes, two sets of multi-size rings are included to fit various shaft diameters.

8. Will these help reduce "jello" in my video? Yes, the high rigidity minimizes blade flex, which is a primary cause of camera vibration.

9. What is the raw center hole size? The center hole is 6mm, adjustable via the included adapters.

10. How many props are in a pack? This SKU includes 1 pair (2 propellers total).

11. Are they durable for crashes? Carbon Nylon is tougher than standard plastic, but because it is rigid, it is more likely to snap than bend under extreme impact.

12. What color are they? They are matte black due to the carbon fiber content.

13. Will these fit a DJI Phantom? No, Phantoms usually use proprietary "self-tightening" hubs; these are for standard threaded shafts.

14. Do they need balancing? They are factory-balanced, but a quick check on a manual balancer is always recommended for professional work.

15. What is the weight per prop? Approximately 14 grams.

16. Is the 3.8 pitch too low for wind? No, it provides excellent torque, making it very stable in light to moderate breezes.

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

18. Can I ream the center hole to 8mm? Yes, they can be reamed for larger shafts if needed.

19. What happens if I install them upside down? The curved "logo side" should face UP; if installed upside down, lift efficiency will drop drastically.

20. Can I use them on a fixed-wing plane? Yes, they are excellent for slow-fly and high-torque model airplanes.
