@Mickele, You can add as many ESCs to I2C bus as you want. In generally one I2C bus can handle 127 different devices / ID's.
@Peter, mixer tables and other I2C support will be added to main code base soon. We are currently busy on other issues. But you are most welcome to add it by you too. There are already working I2C branch under ArduCopter repository. Take a look that, it's under branches/Redfox74
I have just tested the converted I2C ESC's on my quad and things are looking good although I haven't done any exhaustive tests and fine tuning yet. This is my second step to building an Octo. I will now be converting a further 4 Turnigy ESC's to I2C and adding the next four arms and motors.
The I2C ESC's do seem a lot smoother and more responsive than the standard pwm versions but that maybe wishful thinking.
I am hoping that the software changes (adding a mixertable to drive all 8 motors) will not be too traumatic.
I see mixed responses to adding the magneto which also uses the I2C bus although I haven't delved further yet.
Well I had to run few hundred of pages before (and stupid me) noticing the search this topic area lol
Any way I got an answer to my question which was if I can use the Ardu electronics to build a coaxial hexa or octo.
I am completely new to the matter and nub in electronics so sorry in advance for the following few questions.
-Is it a matter of software or hardware?
If software, I will try to find my way and surely share my findings (if any)
If it is hardware, well than I will have to wait for the next releases or try to find another solution,
I placed an order today today for the Ardupilot, IMU, GPS... and they are already on the way.
I wanted to make a copter that is able to carry a 500-1000g HD CAM.
-Would it be possible to achieve such a payload with the current suggested configuration on wiki?
-Or would it be possible to achieve such a payload with different propeller/motor combination while having a stable flying platform, admitting that the build/frame weight around 1000g?
First we get quads working properly and then we move on hexas and octos. There are already some work done for hexa setups on our team but nothing official. Possibly on next release there will be more on this, let's see. At least on next official release we will have our new software architecture in use, basic gps functions and altitude hold. Those are already planned to be on next, if everything goes well we might even have more.

Thank you for your help.
But I am eagerly waiting for it, still deciding if hexa or Octo!
he postet his code in here
i don't know him, but it is hexa config
