Uhhh, what statement in the rules dictates rotors sharing a common axis? Not what I thought I wrote, nor the way I interpret it going back and re-reading.
I think the relevant paragraph you are looking at is para 2.d. What we meant was that all the blades for a single rotor must be in a common plane, not that the axes for different rotors must be common. In other words, a Chinook style model helicopter should be fine (don't know about competitive though).
If we butchered the lanquage so bad that one axis is a common interpretation by event supervisors, feel free to put in a clarification on the NSO site.
Note, if folks feel this discussion is not appropriate to this forum, let me know and we'll take it off line.
