An important question !!!
What is Auto level mode ? Rate Ratetrainer Attitude Axislock or Weakleveling?!!!
I need to give when I stick the bird Automatic Level.
-
Attitude ?

I set Attitude but Quad drift on Hover!!!!
Stick in elevator and aileron is very weak or dead!!!
What is setting in picture for better stability?

What is Ratetriner ?

What is Ratetriner ?
Same link for explanation : https://librepilot.atlassian.net/wiki/display/LPDOC/Input+Configuration#InputConfiguration-StabilizationModesConfiguration
You can also find the Ratetrainer page and others here :
https://librepilot.atlassian.net/wiki/display/LPDOC/Advanced+tuning
Drift can be due to a wrong level settings or simply PID that need to be adjusted.
For basic / primary flight modes, complementary is fine.

I read all and set but auto level not work!!!
What is magnetometer setting?
-
There is no need Magnetometer for Complementary + Attitude stabilization

Are you sure you select the flightmode position 2 ?
Your PID settings are really strange, Yaw should not be the same as Roll/Pitch
Attitude P (outer loop) is pretty high.
(https://forum.librepilot.org/index.php?action=dlattach;topic=3084.0;attach=5330)
Where did you find this settings ? Try default, clicking "Default" button.
In your screenshot number appears strangely, is this chinese numbers ?
-
My Quad is 130mm 1306 kv4000 motor , it be very loose in default setting!!!
I increase PID until fly is stable but axis not to return to level!!!!!
I think is missing from informed regulatory!!!!! :-[
-
Here is the PID i have for a similar setup and 1104-400kv / 130 quad.
Not extremely optimized because i use 2S and 3S battery.

Accelerometers can be affected by vibrations and report a wrong attitude.
You can test statically applying Throttle, maintaining firmly on desk and looking at PFD behavior.
-
- Vibrations / test on desk how react the attitude / PFD.
- Adjust PID, use easyTune / AutoTune
- Reduce Attitude P (outer loop) to default.
- Double check you really use Attitude stab and not using other you configured (Axislock / RateTrainer)
-
Thank to F5soh , the final setup:
-
You should avoid the "Always armed" setting
Adjust your neutrals in Output tab : move the slider to the value where the motor just start using the "Test outputs" option.
No need to quote a message just posted previously.
-
Is the battery wires near the antenna problems?
-
When there is something wrong with your settings, safety checks prevent arming. Setting always armed is bypassing safety checks. You should revert back to not using "always armed" and fix problems that prevent from arming. These safety checks are there for a reason. Check your system health are all fields always green ?

No
Did you mount the propellers with the marking facing up ?
-
Some confusion. :)
Attitude mode is the most common "auto level" mode.
Props MUST be balanced or it can cause it to go crazy.
Without running a GPS, it will always drift, at least to blow down wind and a little random on top of that. That is the best you can hope for. Like a car, you must constantly correct it to keep it on the road.
You must have it flying well before adding a GPS.
Your new quad is like a car that is built, but front end is not yet factory aligned. You must adjust Attitude -> RotateVirtual to align it to minimize the drift. Search forum for "rotate virtual". :)

No
Did you mount the propellers with the marking facing up ?
Yes propellers marking facing up .
The build quality is very effective Prop and balance in flight.
Now I us DALPROP 3blad T3045

This is my Quad :)

Suggest Balancing propeller 3 inches? ???
-
Who does not comment on balancing the motor and propeller?
-
Get a magnetic (suspension) balancer. Be aware that even the balancers are a little out of balance. I balance, and then rotate prop on balancer shaft about 180 degrees and make sure it is still balanced. "Split the difference" so that it thinks one blade is a tiny bit heavier, then you rotate and it thinks the other is a tiny big heavier. That is the best you can do.
Is that what you were asking about? :)
-
What to us other Flight mode by other channels in radio? ???
My Flight mode switch is 3position but I need 5positions.
I need set return to base by a channel.
-
Most modern radios allow you to set up multiple switches to a single channel. That is the official way to do it.
Another way is with a knob instead of a switch.
There are also some switch kits for some transmitters, to add a rotary switch that has many positions.
Be careful if you do the following, there is a delay with turning on a transmitter and probably some switch position safeguards in the transmitter setup: Add an FMS position: Then configure RC failsafe to move the FMS position farther than you can with the actual switch, then just turn off the transmitter. You can also set FC failsafe to FMS position for RTB that is not reachable with transmitter on and switch transmitter off.

It not good more than 3 position on one switch!!!
I need other flight mode by any channel and switch example auto landing crocus lock home lock & ...
-
Some modern radios allow you to "combine" a 2 position switch and a 3 position switch to get the effect of a 6 position switch.

What not to set up other channel for other flight modes ?
What other channels on the controller used?
Is this a weak software?

Any controller has a channel mapping for controls . Combine :(!!!!
