Flight Control System (FCS) - For any plane

How the system works:
The system is based on memory cells (switches that are connected to themselves, they kind of work like accumulated accuators, where if you send them a signal, they will move (change their value), if you stop sending that signal, they stop moving and stay where they are (keep current value)). This allows for the system to maintain level flight, as the plane won't pitch down by itself (system pitches the elevators up until the plane is no longer is rotating down and holds that angle on the elevators).

If for e.g., were one of your wings to get snapped off, same thing applies. it will trim the ailerons so that you don't spin (depends on the aircraft and how much authority the control surfaces have).

There are 2 versions available:
1. Just the FCS (this creation)
2. FCS w/ autopilot (system and camera) (available here)

Both versions have a g-force limiter that can be adjusted/removed (under 400km/h you don't really need it).

Originally posted by Some additional advice:

⋅ Make sure all actuators (other than the rudder) are set to a pretty high speed (5 is fast enough, 100% for flaps), remember to use the correct sign (+ or -) so they move in the right direction.
⋅ Check if your plane is aerodynamically stable (perform the drop test). If your aircraft stays straight or falls backwards when dropped, you need to move the center of mass foward, have more aero moved to the rear, or both. The FCS will have a hard time making a plane fly well if it's unstable by nature.
⋅ To control how snappy the pitch (elevators) is, modify the value of the big blue sensor on the side. 0.4 is default, higher values are snappier and generally better, but setting them too high can create a feedback loop, which will make the plane continuously pitch up and down.
General rule is: Planes with stronger elevators should use values around 0.3-0.5, ones with small elevators (also big aircraft) benefit from higher values, around 0.6-1.0 .
Agile gets don't necessarily want 0.3. I use 0.4 on my jet. Try different values.

A lot of credit goes to Litchytsu, as most planes on the workshop already use his system. That system was originally created by Litchytsu and published in his Super Tucano plane, then copied by almost everyone and used in their own planes. Litchy's system is very similar to mine in the way it works and even in sensor values.

This creation is my attempt at having more people use good FCSs in their planes and making that FCS easy to install and adjust.
