OK folks, just another gentle reminder to everyone involved in this thread: This is an engineering discussion, the pupose of which is to tease out the best design of intermeshing helicopter. I would really hate for it to all fall apart due to differences of opinion/experience. I appreciate that experts are always passionate about their beliefs, but have been in enough projects to understand that it is critical that all agree to some level of compromise.

Dave,
"The Constant Velocity Joint + Hub Spring rotor ... is only a progressive step ... toward an 'absolutely rigid rotor'. "
Agreed. Your rationale makes complete sense, and i accept that my interest in lead/lag compliance is only one possible long term solution - it may not even be the right one! I have eaten plenty of crow myself over the years...
"...no desire nor need for government funding or outside investors..."
Wow, i wish i was in that position!
"The risks are greater but the challenge is more exciting."
Remember there are those of us who are willing to help you share the workload
(if not cost
