FAQ 

Q: How do I pick the correct KV?

A: Lower KV (800KV / 900KV) works with larger propellers and supports 6–8S LiPo. 1050KV / 1200KV are for 6S setups with snappier response and smaller props. Match the KV to your airframe, battery and propeller.

Q: Can I reverse the motor rotation?

A: The shaft comes with CW thread by default. Swap any two ESC wires to reverse rotation.

Q: Is the max power continuous power?

A: The listed max power is peak power tested under 6S. It is short‑term data. Do not run the motor continuously at peak load.

Q: What should I note during installation?

A: Mount the motor with the included M3 screws. Secure the propeller with the M5 nylock nut. Always check prop tightness before flight.

Q: Can I use this motor after water exposure?

A: This motor is not waterproof. If it gets wet, disassemble, clean and fully dry it. Inspect bearings and windings before flying again.
