I have read the ArduCopter online manual and it would be really difficult to build from the available material if you had the complete kit.
For example, one picture shows the motor wiring routed in the frame, another outside. The distribution board shows the ESC's mounted one way, another shows them tie wrapped to the frame. Nothing shows exactly how they should be connected. Very small example of tons of discrepancies.
I realize it is a work in progress, yada yada yada.
What is shipping with the complete unit? If it is different why isn't it available here.
If it isn't different I pity the fool that hopes to fly.
