The reason why they don't push might be becausethemotors are constructed
that way (the carbo things conducting the current to the rotor)

I'd love the finished circuit, but I don't know how much help I would be
:-)
What kind of problems are you having, and what kind of work do you think
is needed to solve them?

Sorry for my anger, but my emailbox jammed, because there were to much mails

I,m relatively new, but isn't it a good way to simplu not make any
mechanical connections to the outside? Have you ever seen a magnetic stirrer
at a chemistry laboratory? it works like this: rotate a magnet with your
motor in the shell, and it willrotate a magnet outside the shell, connected
to the propeller
