Hey Kevin,

congratulations about the implementation of the VTOL UAV in paparazzi. I am very curious about how you set up the paparazzi environment, as I am also looking for a transitional UAV solution.

My guess about the ESCs is, that you're facing an issue of ESC calibration, rather than paparazzi control. Did you calibrate all ESC as described in the manual? You may also check out the post about Turnigy multistar ESCs on DIYdrones (http://diydrones.com/group/arducopterusergroup/forum/topics/problem-with-esc-calibration).

Hello everyone,

It was quite successful today. I managed to compile and upload the
airframe.xml. I did bind the receiver and it seems to work so far. The
problem I have now, is with my ESC's. Just 2 of 4 are spinning.

I think I already know what could be a reason, but I do not know how to
solve it. Somehow, I have two slightly different kind of ESC's, some mixup
with Hobbyking I guess.

Although they should be both working, only the top one does. They both
support form 2S up (I am currently using 3S for testing, later it will be
6S). The top one has the Signal and Ground Cable coming out, the bottom
Signal, Ground, and VCC.

I checked the Supervision too, but all throttel is set to 256, so this
should be fine.

Here are the relevant pieces of code:

      <subsystem name="actuators"     type="pwm">
        <define name="SERVO_HZ"       value="480"/>
      </subsystem>

  <servos driver="Pwm">
    <servo name="FRONT_TOP"    no="0" min="1000" neutral="1000" max="2000"/>
    <servo name="FRONT_BOTTOM" no="1" min="1000" neutral="1000" max="2000"/>
    <servo name="BACK_LEFT"    no="2" min="1000" neutral="1000" max="2000"/>
    <servo name="BACK_RIGHT"   no="3" min="1000" neutral="1000" max="2000"/>
 </servos>

Is it possible to make both ESC's work?

So far,

Kevin
