Hello everyone, if only the final orange silicone part of the propellers is slightly scratched, should you change them?
Thank you

Maybe if there is a single scratch, but if there are any chips you should definitely replace them. Also check if any if the props are warped.

3 changed and 1 seal, could I only change 1?  or is it okay?

Hi there. Thank you for reaching out. As per checking on the image that you sent to us, it shows that there is no issue with the propellers and you can use it as normal. We strongly recommend replacing propellers if it does damage like a crack or broken plastic. You may try to test flight your unit and hover it in place to check the stability. Please keep us posted. Thank you.

very well thanks, then I also keep those disassembled for a future replacement.
