Oh yes, I have used mechanical brakes and have a pair of new unused
DuBro electric disk brakes a friend gave me some years ago. I thought about
using them on a scale project but never came up with a variable voltage
power source. As small as they are the on-off switch would probably work
just fine.

Yes, we did keep them running until the airplane was in the hangar.
BTW, we also used brakes back then too, so we could demonstrate taxi
and a full stop just before takeoff. Then we had to come to a full
stop (straight ahead) after landing, before taxiing back to the
hangar and stopping in the hangar. Just producing brakes was a
"cottage industry" back then. I still have some mechanical and
electric brakes in a baby jar somewhere.
