The difficult part of this simulation is to find the correct elevator surface. The software only take into account a traditional control surface behind the hinge. So I had to compute an equivalent surface.
I first ended up with a value of 20x30 cm but then discovered that the center of lift of the control was close enough from the rotation axis to use 15x30 cm ( check the values in the non optimized elevator setup ).
Guys if you find something better, let me know.

The main purpose of this exercise was to show that the conventional setup for the elevator ( symmetrical pull-pull setup ) is reaching the DS8711 limits extremely quickly.

As a matter of fact, with these sizes of jets and no matter what brand, we are reaching the limits of the best servos available on the market for integral elevator control.

My conclusion is that the elevator system setup is critical. So is the battery system that will drive these big consumers at full load.

I have had a report of a person crashing a big F-16 due to an elevator failure. This is the reason why I did this computation.

Once again, here is the setup that I use on the F-18F:



The binding is controlled by offsetting the servo side application points of the ball links forward of the rotation axis by 15° ( not shown on this picture ). This needs a specific aluminium servo wheel available here:
