I am unable to arm my pixhawk 2.4.8

ArduCopter Copter 4.5

I tired every possible way but i am unable to arm my pixhawk

  1. Update to Copter 4.5.2 or 4.5.3-beta
  2. What prearm messages do you see in the gcs?
  3. If there are no messages, set LOG_DISARM = 1, try again and upload the log
  4. Upload a .param file with your parameters
  5. What methods exactly did you try?

This isn’t a magic show where you get a miracle answer without us knowing anything about your problem. If you expect a magic show like answer what went wrong, my guess would be “user error”.

If you’ve tried every possible way then something is preventing you. Fortunately in 99% of cases that something is very easily identified by reading the documentation and observing what your autopilot tells you: Pre-Arm Safety Checks — Copter documentation

What you should NOT do is disabling the pre-arm safety checks. They are there for a reason, and your autopilot refuses to arm because something isn’t right that you need to fix.

Hi pixhawk drone is armed but my drone is constantly flipping on backside. I did esc calibration many times but still the problem persists. Please help me out.

Can uu please guide me out where i will get .param file? Is it saved on sd card?

Go to Mission Planner → Config → Full Parameter List. In the top right corner there’s a button “save to file”. This button generates a .param file with all your parameters.

regarding the flipping of the drone:

  1. check AHRS orientation
  2. check motor order and direction in Mission Planner Motor Test

YOU send the forum YOUR parameter file.
But it’s usually wrong Motor Order and direction from not using Mission Planners Motor Test to determine if it’s right.
The parameter file will not show this but post it anyway.

Every drone is different, you can not take the param file of one drone to fly another.
Even if the Hardware is the same, the accel, gyro, compass, baro, temp calibrations are not.

Flying your drone with the parameter file from another drone is negligent at best and stupidly dangerous at worst.

@Ritobrata_pal use ArduPilot Methodic Configurator software to create the parameter files based on your vehicle components.
Tell ArduPilot Methodic Configurator which components you have, instead of posting them here.

You can’t fly a drone with 15 inch props safely without properly tuning it, and this is a dynamic process where you can’t just hack in a couple of numbers and you’re good. Even when tuned, a drone that size can seriously injure someone or worse, if handled improperly or without safety measures in place.

With smaller whoops I’d say go ahead and learn by doing/crashing, but not in this case.

there are the gcs log at present

That log is irrelevant. We need a Screenshot of ArduPilot methodic configurator.

Please read my first answer again. And do it
Stop waisting your time. :wink:
