Motor for remote controlled antenna tuner
 

I'm considering building a remote controlled balanced tuner. Some type
of low RPM motor 12V reversable motor is what I have in mind to accomplish
the tuning. I will have two fairly hefty variable caps to turn along with
a moderatly sized roller inductor.

Can anyone here recommend a particular type motor, and a reasonable
source for the the type of motors I need? Tnx.

Try these;

They have a lot of torque, and are used in robotics a lot.

Thanks, Bob. They all look like about what I had in mind. Probably will
order something to try in June.
