Updating the theory that mikado uses different tail rotor hubs i want to say that there are really 2 types.
But the difference i"ve noticed is in depth of hole drilled for hub bolts.
Some of them have almost exact depth of bolt thread(a half milimeter deeper) and some of them are drilled couple of mm deeper.
I don't know if that difference affects on tail wag and some other measurements are different or it machined different.
I never had tail wag on logo but i own 690 and friend of mine 600.
But tail assembly is the same for 550 600 690
