Hi,
As someone who is utterly unfamiliar with rotary wings (apart from a hysterical romance with gyros some years back), I have a question regarding coax helicopters...
Coax helicopters proliferate the RC world, where they are rediculously easy to fly. We had a few quad copters and a small coax helicopter in the office once, and they quite literally fly themselves if you add a bit of power. Nothing could be simpler. Rock steady in the air. However, it seems that this simplicity does not translate to full size helis. Why is this? Surely the aerodynamics translates? Physics is physics, after all, even taking Reynolds numbers into account. And yet the web is littered with failed attempts to produce a viable coax heli.
I don't get it. What am I missing?
