I bought some cheaper copies of propellers off aliexpress. And I've been using them a few weeks before the earlier firmware update. I've noticed that the off-brand propellers have thicker blades. And after the recent firmware update, the drone has vibration that I can see jello in the goggles feed. It also makes more high-pitch noise and sometimes resonant noise. Also I found two weeks ago that one of my motor's bearing was bad. But this may be resulted from my crashes and perhaps aggravated by the use of off-brand propellers.

Long story short, I replaced the bad motor, and change back to original propellers, and the noise was much less and I could hear that the propellers respond to abrupt PRM jumps much effortlessly. I think the original propellers have these very thin (almost feels fragile) blades for a reason (to mtach the motors and ESCs tunning for better RPM accerleration and decelleration). I also suspect that with the new firmware, they might tuned the propulsion system more aggresively (not in terms of overall thrust output, but rather the accerleration of RPM) so that heavier off-brand propellers will work even worse.

Does anyone know or tried any off-bran propellers than work as good or better than the original, and cheaper, of course?

OrginalDobo on YouTube made some videos about after market props,  many he had issues with, but he did find one make he like,  might be worth checking his channel.

I will never understand why people would use after market blades.  The cheapest, yet most important part of the drone.  People, please do not use after market blades, you are not saving anything.

LOL, another youtuber with his mouth wide-open. Sorry I am not gonna click on his video. And I am not gonna use aftermarket props.
Just think: Would you use cheap tyres on your expensive car?

Exactly, the most important yet cheapest part, and people feel the need to try and save money.  As some one here might say... If yu cannot afford the props, then perhaps this is not the drone for you.

OEM = Original Equipment Manufacturer - DJI you conflicted yourself lol

Thank you for the reminder. Currently I'm using the original propellers (and found these to be the best so far).

It's ok to be unable to understand. I guess people have wide variety of reasons. Not really for saving the cost, just trying options.

Interesting thought. Not really to save money for myself, just tried cheap ones to begin with.
