Looking forward to the next article about all moving tails since most of mine have AMT's as will many scale jets

The next article is much more technical.

Here is a sample of what can be done to simulate all flying stabilators:

This is useful to confirm the position of the CP depending of the AoA. The excursions of the CP will dictate a position of the pivot point. As usual it is a trade between flying surface stability and servo efforts.

The CP position is shown by the big green arrow and the XCP vlue at the bottom right.
The lift field is shown in green.
The viscous drag field is shown in magenta. Inviscid drag is not represented here for more clarity.
