And that is the whole basis of this discussion.

Chris: Can we agree that there are three types of controls?
1. The pure electronic CCPM as you describe (as in the TRex),
2. the one that somehow mechanically, the swashplate moves up and down for collective control (as in the Raptor), and
3. the one where the washout base (or other parts of the head) is the one that controls the collective pitch angle, but the swashplate does not move up and down for collective control (as in the Kyosho Concept).

Can we at least agree that those are the 3 types of controls?
