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?
