First APM2.5 build not working fine

Posted by Tono on September 3, 2012 at 12:23pm

Hello,

I am new with APM2.5 and I am having problems to fly my quad.

I am using the X orientation.

This is what I have done until now:

1) Calibrated ESC's (automatic and manual calibration)

2) Checked propellers direction and position

3) Changed PID values, started from 0 (stab and rate values) and increased them as specified on this link:

4) Calibrated the radio (futaba 7c), the accelerometer offset and the magnetometer.

I am trying all this in stabilize mode, so I'm not involving the GPS (I guess)

I am not sure what else to check, any ideas?

You can see its behavior here:

    I found the problem.

    All channels in the radio where reversed.

    I inverted all of them except for the throttle and now it flies.

    Too bad I moved all PID's for stab and rate to zero... now I have to tune it :)
