Hexacopter spins outof control just on takeoff, using pixhawk 2.4.8

i am a complete beginner to pixhawk and got pixhawk 2.4.8, on YT it looks so easy to build the drone with this but I am having one hell of a nightmare. the drone upon takeoff is spinning CW and slowly increasing in speed and crashing. the ESCs also beep out of sync slowly, the motor and the props are correctly placed. i am using S550 frame. i have disabled the internal compasses and am using an external compass. i have the log file can anyone help me out please.

You could help yourself, or wait for someone to look at the log

if i could help myself i would have…i tried almost everything I could find on google…yet none worked

You did not try the link I posted, did you?

oh, sorry i did not…will do it now…and btw my heading in MP without the GPS module is rotating…slowly CW

The flight controller can not operate correctly without the GPS module.

shoul i try flying without the compasses enabled?

No, you should try using the link I sent you and perform the steps correctly.

okay…but if anyone does see my log file just want to know what I did wrong…

Usually it’s a multitude of things, just read some posts on this forums to get a feeling for the common mistakes! And nobody likes to repeat himself.

buddy…that’s y the log… :sweat_smile: :sweat_smile:

That’s why the software. To fix all the issues in one go. Semi-automated to make your live easier avoiding repetitive clicks and avoiding having to install multiple additional software!

okay dude…chill…will try that out first and get back if any issue persists…thanks :grin:

It also fixes problems that you do not yet know you have!

well then i appreciate this help…i avoided this software cause it looked…complicated

It has four buttons:

  • Add a new parameter
  • Remove the parameter next to it
  • Upload to the flight controller
  • Do not upload to the flight controller.

Explain what is complicated about that?

:sweat_smile: :sweat_smile:give me a little time to learn…

You could start by using the correct firmware. fmuv2 is not correct for anything. Use fmuv3 or Pixhawk1, this depends on which shitty version (because they all are) of the 2.4.8 you have. Does it say Radiolink on it?
There is plenty more to see that is wrong but no point in doing so as The Configurator will sort it out.

i am using s550 frame and readytosky 40A ESC. i have 920kV motors and a 3s 5200mAh battery. the motors and ESCs are perfectly fine, checked them on a quad, but as soon as I solder them on this hexaframe, the servos don’t give out constant output and even after ESC calibrations the motors don’t start up in sync. i even used DJI Naza m lite and even in that this issue is there.
