Please do'nt trash it!!!!
The Unimite is an Eveready Tornado motor driving a screwed rod with a tapered screw thread at each end so the screw imediately picks up when put in reverse.
It is to operate the rudder, I seem to remember that they do self centre, but were meant for pre-proportional RC just switches. I think this one is a toothed rack driving a cog internally to give the rotary motion,
The wind up part I have not seen before but it looks like it is working a switch for forward and reverse for the Taycol motor. If you take it out you will see the name of the motor on the brass angled plate.
Taycol motors had field magnets and needed current to produce the magnetic field, Reversing the current does not reverse the direction of the motor,
You have to reverse just the field windings only.
They create a lot of radio interference apart from on 2.4 Ghtz. I have never tried this.
There is a helpful web site devoted to Taycol.
By all means remove and replace.

Roy
