Hello guys,
when using the motor test application in mission planner, Motor 1 and 4 are working accordingly (they are available through the buttons labelled "A" and "B").
Please have a look at the following naming conventions (nothing new...):
By pressing button "C" and "D", nothing happens beside the light of the Pixhawk flash as it should be.
Have a look at the video and you will understand:
----
0 - 27sec:
First "round" in motor test:
5% throttle, 2sec
First and second motor spins by clicking A and B.
Motor C and D are not spinning, even the blinking light is indicating that.
On press "Test all motors": A and B are spinning only.
35sec - end:
Second "round" in motor test:
10% throttle, 1sec
On press "Test all motors": After a while, all motors are spinning.
Motor B alone spins.
Motor C does not spin (watch the light...)
When pushing C and directly afterwards D, both motors start spinning...
----
An equal behaviour can be observed in stabilized mode:
-----
0 - 20 sec :
1. 0% Throttle: Motors spinning equally.
2. Giving a little bit of throttle: Pixhawk starts stabilizing.
3. Mixing in some left and right roll: Quad banks to one side as it should.
20sec - end:
Instead of roll I used pitch.
You can see the quad twisting, because left Motors are not reacting to input.

Additional info:
PixHawk with Copter V. 3.3.2
ESCs are flashed with BLHeli
ESCs are correctly calibrated (numerous times)
IMU/Compass as well...
The problem is channel related! Switching the channels will give the same reaction with other motor.
Any suggestions?

Found the error by myself:
ESC Output pins 2 and 3 where soldered together. This was a factory error.
This unit is NOT an original 3DR Product!!
