As to using a homemade control and display leave that to others.
The X-5 has no
clutch control signal, but a toggle switch and 12V could solve this.
The X-5 has a advertised continuous rating of 5 or 6 amps. When I
work through the schematic it looks like the overload sense threshold as about 10 amps (how long ??). The transistors driving the
motor are capable of more, but the X-5 monitors the
motor current. One could fudge this slightly with a few resistors and a soldering iron.
The actuator
current draw is a function of
rudder forces and system /configuration inertia. With the smart pilots including rate sensors often inertia is a bigger
power issue for a lot of craft/ conditions.
The X-5 is a sophisticated piece of
electronics (I ran one for years driving a Benmar rotary actuator), but it was on a light
helm craft and configured for minimum rotational inertia.
Pays your
money and take your chances.
Frankly
