Dave, that link has some good arguments regarding perceived problems to an intermeshing rotor, but it doesn't provide any argument as to why the intermeshing rotor would be better than a tail rotor.
I think the intermeshing rotor may prevail in certain roles. Heavy lift is an area where it may shine. Tandem rotor has proven itself there, and some of the same benefits come from intermeshing rotors, with different drawbacks.
What exactly are your reasons why you believe an intermeshing rotor is better than a tail rotor?
