ekf2 imu0 ground mag anomaly, yaw re-aligned

Now hexacopter can fly. But after arming the flight lost signal from herelink transmitter and flying without any control from ground or cut the signal from ground.

ok then there are exciting problems as follows

  1. loose connection herelink system.
  2. After taking off some interference is coming from the power system.
  3. Update herelink firmware.

note: Give separate power supply to herelink Air unit (using 2s lion battery)

please change share setting to all peoples

We actually fly our copter with stable before we adding our payload(gimbal and thermal camera). After first flying with payload, the copter lost its flying stability. Initially we used same power for both controller and payload. After losing stability we used separate battery for each payload and controller.

Please change the permissions of above drive link

you need to tune the copter with the payload. if the payload is soo costly then, use a dummy payload weight instead of the original.

Now we did not use payload. The copter did not maintain its stability in flying and fly without any control.

The attached .bin log is testing without payload.

You will need to configure “RC failsafe”

vibrations are a bit high please as follow

  1. Use anti damping flight controller mount. or please follow below link
  2. Tuning the Harmonic Notch

We can attach another .bin file of crash.Can you check the .bin file.

when this crash has happened, Please give permission to the above link. every time I asking you, is my time weast.

we sent the .bin file. The crash happened last week. After crash We calibrated(ESC, radio calibration and compass calibration). Then, yesterday we again took flying test.

we had used anti damping flight controller mount also.

@Anooja_sukumaran Vibrations are there in your system.

ok. But why did the copter fly without any control when arming and also did not respond with transmitter?

This is the last flying test video. The copter moved up when arming, but the throttle did not move high.

I am not able to study your log. Do one thing give the small mission and observer vehicle.
