Motor falling behind

Hi.

I build a quad, and i use arducopter to run this.

I have done all the calibrating, but when i use the throttle one motor is starting up a second after the other 3... I have not done anything with the ESC, i tried to connect a programming card to see if the ESC had some other programming, but the ESC didn't support programming card...

 I use this  [url=http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=4204]ESC[/url]

and this  [url=http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8622]Motor[/url]

 

I am about to test tomorrow when it's less windy to see if it matters... Today it just drafted to one side, but if i tried to tilt it back it worked...

 

 

Thanks.

  • I don't know whats happening here...

    I have tried everything and still it freezes when trying to use the radio...

    But in the setup when writing radio nothing happens... shouldent it at least tell me to press enter when i have done moving the sticks to it maximum?

    But how much voltage does the card take?

    I connected a 3s lipo 11.1V directly at the board and with usb all was ok, exept the radio didn't configure, but when i removed the usb the lights on the APM dimmed down, so i removed it an gave it 5 volts, and then everything was as before...

    Nothing smells burned or anything :P But if i have broken the card, how do i find that out, and witch card do i have to change?

     

     

    Thank you for helping... This is expensive equipment, and i really hope i haven't broken it...

  • calibrate accelerometers

  • I tried to do as the user manual said about calibrating. This did not work. When it where in auto all the esc beeped the same, after manually calibrating they didn't...

    I reset the card to try to start from scratch, but after loading the firmware i press the bottom button and start with step 2.

    It now tells me to insert battery in RX and turn on my TX, i do this and it asks me to use the controls to max. After this before i got a new window telling me how the results are, but now it just freezes, and as i read in the manual this is caused by the RX don't have power... I unplug the RX from apm and connects a servo, and it works as a charm...

     

    Confused...

    You need to calibrate the ESCs manually. Instructions are in the manual:

Excellent use of cardboard instead of 3D printing! https://twitter.com/Ingmar_Stapel/status/1324960595318333441
