Hi
I completed setting up the bird, but the problem is that the ch2 OUTput in APM is not working (PWM), I read here that I could change the pin to any other ch output like 6 or ch7.
But am getting many errors

here is the list -

So what I did is I changed the library file   -  AP_Motors_Class.h

But it dosnt compile and gives the same error everytime, EVEN WITH THE ORIGINAL SOURCE FILE IT DOSNT COMPILE AND GIVE SAME ERRORS
Please help
Thanks

Dear Rahul,
Why don't you erase the eeprom and reflash the firmware with the latest version arducopter  3.1.3.

Asutosh

Autosh , that wont make the desired changes though.

Anyway, after a lot of reasearch at programming level of APM, I finally did it

Thanks

hey can you help me with my problem ?

https://www.youtube.com/watch?v=SbleSREn2Ew&list=WLdWjlIyXeFXxy_vDRrNheOg&index=42

the video shows exactly what my problem is. and this happened after i did the compassmot

Surely looks like ESC calibration issue!
follow this tutorial for ESC all-in-one calibration-

I did all of that!

strange, do some research, ask in rcgroups' APM thread.. I am sure there are expert people

No one replying

Regarding the initial errors mentioning Compass,

There is no on-board compass on the APM2.6.

If you're not using the compass, disable it in MAVlink while calibration, to get rid of the errors.

If you're using the compass, you'll have to purchase an APM-compatible 3-axis compass breakout board and hook it up.

Are you using the Arduino Arducopter IDE to program the APM?

Yeah I am using arduino arducopter IDE (modified), the problem I mentioned above was solved when I downloaded and compiled the AC 3.0 from GIThub
