Hi,
A few years ago I purchased a couple of what I believe are small prop
pitch rotors. Now that I have a need for them, I am trying to figure
out how to test them. One of them I was able to use some of the ideas
on K7NV's web site to get turning with my 13 volt power supply. It
turns at about 1/3 rpm. The other prop pitch seems to have a brake in
it, and I have been able to get the brake to click down (though it seems
that it takes a lot more current than the other one's motor does), but
the motor doesn't move. I have removed the aluminum housing, but not
the motor yet. I think I have the right wires as there are three which
look like they were used before, and according to K7NV there is a common
and the other two determine which direction it should turn. I think
this prop pitch was used to turn a Sky Needle in the past. Anyone have
any advice?

Rob, KL7NA
