I get the error message during flight. "engine idle, make sure propellers are installed" warning

Even if I get a warning, I can fly smoothly and land safely. the error makes me nervous during the flight. The same problem occurs on low flights. everything is smooth on my plane, the propellers are firmly mounted. has never been dismantled. the plane never crashed. Can you help me?

For each motor, post photos showing the tops of the screws in relation to the tops of the balde hubs. I think the tops of the screw heads should be flush with, level with, the tops of the blade hubs.

Thank you. I checked the sapling trunks, they are all normal. locked tightly. I get this warning intermittently during flight. in windless conditions. It's a very new device. It's been 1 month since

''Sapling trunks''  has no meaning in this sense, it literally means the trunks of young trees.

You asked for help and that is my assistance.

Hi, djiuser_Vr28YTxGqObU. Thank you for reaching out. Please follow the troubleshooting steps below:
1. Please check whether the propellers have been attached. If not, please attach the propellers correctly.
2. Please check whether the propellers are damaged. If so, please replace the propellers.
3. Please check whether the aircraft was flying in a high altitude area or if you have pushed the control stick with excessive force. It is recommended to try to fly the aircraft at a lower altitude.
4. Please check whether the aircraft is mounted with additional payloads, resulting in insufficient propulsion. If so, please remove the payloads.
5. Check whether there was strong wind during the flight, causing the aircraft’s attitude to become unstable. If so, please avoid flying their aircraft under strong wind conditions.
If the issue persists after the above troubleshooting, please send their product back for proper diagnosis.

I am so glad you helped. I will take pictures and share them with you.

better photos than mine lol.
I don't see anything wrong there.

I carefully inspected my plane. As the left front engine body rotates, the gap between it and the wing changes. There is no strain on the engine. No vibration during flight. When the engine is rotating, the gap between it and the wing changes when you look very carefully. Sounds like you have a balance issue. Is there any harm to the plane?

Do you mean this gap changes?
If so, can you feel any wobble in the rotor?

yes i am talking about there. When I turn it manually, the spacing distance changes. no noticeable jolts to the engine and aircraft while the aircraft is running. no coercion.

I applied pressure to the plane while the plane was in the air for test purposes. I got an e s c error to see the strain on the engine or the error. The picture is below. Then I replaced the propeller with a new one. I put pressure on the plane again. I stepped on it and pulled it forward and backward. I got an error from a different engine, not the same engine.

Translate.

I think that is suggesting that the propellers are deformed and not providing the lift they should at their correct speeds.

The attached photo might be a better translation though it is from a Mavic Mini thread.

If your propellers look flattened, choose the motor with the most flattend looking props and change both blades on that motor with new DJI blades from a sealed pack, keep the old blades with one another as a pair. You MUST change both blades because they are supplied as weight matched pairs. Test fly the drone and see if the problem disappears. If not change both blades on the motor with the next most flattened blades, etc. etc.. until the fault disappears.

Hello there. Are you still getting an esc error even after you finished with your tests? If so please check whether the propellers are mounted properly and whether the motor is functioning.

Try to restart the aircraft and use DJI Assistant 2 to refresh the aircraft firmware. You can download the DJI assistant 2 by going to dji.com/downloads (Do not try to restart the aircraft too many times, as this may result in the aircraft log being overwritten). If the error persists, we recommend sending the product to the Repair Center for testing and repair.

what do you say about this situation? Will it damage my plane?

As in post number 14,  can you feel any wobble in the rotor?

I don't feel any noticeable wobble

I tested the last throttle by running it without a propeller. they all stood together. didn't give an error


by replacing the propellers. I tested it by manually forcing it left and right during propeller flight. e s c motor error . I got a fast turnaround warning. The balance setting indicates a faulty motor. When I checked after landing, I saw that any of these engine temperatures were higher than the others. however, I don't experience any noticeable jolts during normal flying. His movements are quite natural.

hello how can you follow the engine rotation speed. rpm values ​​from log records and or dat. How can I see the output files? my plane dji mini 2 se

You probably can not. RPM are recorded in the DAT flight logs and it is likely that both DAT's are encrypted.
To check this download and instal CsvView
https://datfile.net/CsvView/downloads.html
and try processing the DAT from the screen device.
Do not bother with the DAT from the drone, that is even more likely to be enctrypted than the DAT from the screen device.
The txt flight log DOES NOT record motor RPM but it does record battery amperage, you might be able to deduce something from that but you would need to investigate the correlation between rpm and current for these type of motors.

The only FLY app using drones that I know of that create readable DATs are the Mavic Mini, Mini 3 Pro and perhaps the FPV.

If it is just general interest then I guess the Mini 2 SE has similar rpm to the Mavic Mini. From memory a Mavic mini hovers at around or slight 10,000rpm, I might have seen peaks around 16,000rpm but they would be rare. I am more confident I have seen peaks of 14,000rpm.

You might be able to read rpm with an optical instrument that was aimed at one propeller. If that requires a reflective surface on the propeller I would suggest you put equal amounts of reflective material of both blades of the studied propeller, IN IDENTICAL PLACES, at these rpm the centrifugal accelerations are significant and balancing is important.
