Hi all,
Can anyone clarify this for me? I'm setting up a new Hex in X orientation, I have the motors connected in the layout specified here:
https://code.google.com/p/arducopter/wiki/APM2_Motor_order
...but when I run the CLI 'motors' command it runs in 5,1,4,6,2,3 order (i.e clockwise starting from 5 instead of 1), then pauses before starting again with #5.
I know when I run the command on my quad it starts with motor #1 and goes clockwise, so wanted to be sure before going ahead.
BTW, it feels wrong that the running order on the CLI motors command isn't the same as the motor numbers, wouldn't it make sense to run the motors in 1,2,3,4(5,6,7,8) order rather than going around clockwise?

Thanks for confirming, thanks Marco.
I just find it strange that there are two different numbering systems for the motors: one for the controller and one for the CLI test. I always put little stickers on the arms to number the motors, so it would be easy enough for me to follow the sequence in controller motor order, but I guess you're right, others might find that confusing.
Thanks again.
Hi Andrew, from the wiki (i've write this section and adapted the code for this test):
5) The motors will now spin in sequence, each motor will spin for less than 1/3 second at very low throttle and then stop, before the next motor will start after 2 seconds (3 with Y6 and X8). Please observe direction of rotation of each motor to ensure it is turning in the expected direction. First motor to spin will be the one located directly forward in the case of + configuration, or the first motor to the right of straight forward in the case of X configuration. The motor test will then proceed in a clockwise rotation. In the case of X8, it will spin the top front-right motor first, then the bottom front-right, and proceed around with the same pattern. OctoV will spin the front-right motor first, and then again, proceed clock-wise until reaching the front left motor.
So 5,1,4,6,2,3 (and then pause from 3 to 5) is the right order for X-Hexa.
It's much easier to follow than the progressive motor numbering, it's easier to verify the motors spin in sequence in clockwise direction rather than in the numeric order of the wiki image... no?!
