Hello. I am following the wiki to calibrate the ESCs for my ArduCopter hexa ready to fly version that arrived this week (http://www.udrones.com/product_p/achrtf1.htm). It has firmware "ArduCopter V2.8.1" from the Mission Planner 1.2.14 mav 1.0.
So far I have done the automatic calibration (http://code.google.com/p/arducopter/wiki/AC2_ESC). It seems to work, and after I am done, all 6 motors work when I move the throttle. However, the "arm" and "disarm" features do not work when I move and hold the stick to the bottom right/left. And when I remove the battery, it resets and I must calibrate again.
The wiki mentions that this is a known problem:
Note! After performing an Automatic ESC calibration, (even if the motors seemed to operate correctly immediately after setup,) but do not initialize after power off / on sequencing (ESCs still beep quickly and continuously) you will need to do a Manual ESC calibration sequence as described below."
Which leads me to think that now I must do the manual calibration. But I am confused about how to do this. Each ESC has a red/white/black 3 wire connection that I need to plug into channel 3 of the RC receiver, but how do I do this? Do I need to take apart the bottom of the hexacopter to access the PDB, and if so, which of the pins on the receiver (it's the AR8000) do I then plug in the red/white/black 3 wire connector? Any help would be greatly appreciated.
