Jeff,
Thanks for the clarification. I don't know if this interpretation is held by
event supervisors but seems to held by most SO helicopter designers. Some of
whom seem to go out of their way to align the rotors along a common axis.

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.
