This photo shows only two throttle levers.

This is my 2nd throttle lever.

Flap lever mechanism. The cener motor is the geared motor for autothrottle.

There are two stoppers on the same position as the real one.

This is spoiler lever. I added one more motorized potentiometer for more power.

This is the mechanism of auto throttle. Very simple!! The power of shaft is conducted to the levers by nylon washer.

Now all parts are assembled.

lateral side view for flap lever. Two coiled springs are used.

Upper side of the throttle box.

Installed in the box.
