Problem with servos

Posted by mosquito on June 4, 2015 at 11:23am

Hi. I have a problem with apm2.5. I install this autopilot in my new plane and servos dont work. I check connect them to receiver and they work ok. Although with output apm they don't work. I followed all steps ...Does exist any parameter?

My best regards

    Are you using the latest firmware? 3.3.0? It has a arm / disarm feature now.

      Yes I use latest firmware 3.3.0.

      I introduced ARMING_REQUIRE=0 and APM was armed.

        Do the servos move at all when you power up (twitching or anything)? If not, check with a multimeter that you have voltage on the + / - pins coming out of the APM.

          Output voltage is 1.44 volt

            Ah so obviously you're not supplying enough voltage, power the output rail with 5v.
