Dave,
Your discussions are always intresting, but I am beginning to want to join the "shut up and build the damn thing" camp.
We have continually discussed your concepts, and it has be an enlightening journey. It is getting a wee bit reptetive now though! We have discussed your ridgid blade concept in much depth - and you remain unconcerned by the practicalities, let alone the physics of the thing. If you can make it work, you will revolutionise verticle flight - so get to it.
I am not convinced that all technologies can become due for a revolution as you seem to suggest: the wheel still works pretty good. Maybe the single main and tail concept works alright for the time being.
I await the gloosy brochures and the video tape of your first test flight.
