Hello Garry and Phil,
I was thinking about a model radio control set to do the moving
of a slide switch with a servo also.
Those wireless doorbells may work up to 100 feet if they had
a little bit of help from an additional antenna.
I can't remember if the bell part of the system plays a tune
or buzzes according to how long you press the door button.
Anyway the wireless link is reasonably cheap and a relay
could be fitted to switch some sort of clockwork or rubber
band escapement just like the old RC models.
Left neutral right neutral left neutral right ....and so on.
Press and hold for left
Press release press and hold for right
Press and hold for forward
Release for stop
Press release press and hold for reverse.
That is super cheap radio control.
You momentarily get forward before you get reverse.
The servo is better.
Gary, just out of interest what are you doing with the motor?
