  I suppose the channel assigns for Spektrum are the same as JR?

  Yes This illustration will be updated after public alpha release is out. In final version of this illustraion, it will contain channel information. Here they are as in text:
  
  IN0 = Aileron
  IN1 = Elevator
  IN2 = Throttle
  IN3 = Rudder
  IN4 = AUX1
  IN5 = AUX2
  
  This same information can be found from code it self and should be... again .. Should stay as is now ... but due we do not have yet public alpha release i don't put my head on it yet :P

  I'm a JR user and the channel assigns are different. Can you tell me the channel assignments in the above diagram (ie what signals are needed on each of the ArduMega inputs)?

  As I'm a Mac user I use OmniGraffle to do my network/documentation/design and other sheets. You can do similar documents even with M$ Visio.

  This is a cool-looking diagram. What program did you use to make it?

  Well there are only 2 possibilities to put them... When you start your engines and your props "blow" up, change their order. They should all blow downwards :)
  
  Some companies calls their props pushers even they are pullers and vice versa, so it's better not to say that pushers always goes on "these" motors and pullers on those... Best way is just to test or when you are about to mount them, think which way motor is running and look your prop, you can figure it easily. Like I said they all should blow down.

  Excellent diagram, Jani--super helpful. I'll integrate into the ArduCopter manual.

  You need to have both Pusher & Puller props. This is due we are using centrifuge forces as our rudder. So if all motors are spinning on same direction, whole quad will spin on opposite direction. Having 50% CW + 50% CCW motors we can counter measure this spin and also we can it to rotate quad. By speeding up other group a bit and slowing down another, this way our total thrust is still 100% but we are turning. Controlling speeds on these groups we can easily spin it which ever way we want.
