50.0. "electric motor break-in" by HOMBRE::DAUGHERTY () Thu Jun 18 1987 23:14
Dan
Ten hours sounds like alot, but Kyosho should know. I understand
that a common practice is running the motor (free running, no
gearbox, clamped lightly in a vise with styrofoam on either side)
on two new D cells (3V?) taped together in series for around three
hours. Keep checking to make sure it doesn't overheat and, if it
does, disconnect it long enough to let it cool. I don't believe that
breaking it in at 7.2V is a good idea. I haven't gone through this
process with motors, (I was happy to see a recently purchased Reedy
included a note indicating that it was broken in at the factory,
maybe that's why they get so much money) but I have spent in excess
of 5 hours breaking in transmissions.
So sit the kid down in front of the bench with a handful of cheap
flashlight batteries for a day, it builds character.
It's a fast motor, have fun.

| Save the batteries $$$....
It seems to me that I recall reading that your battery charger can
be used for braking in you motor. You simply limit the current
going to the motor. The 3V breakin spec is most likely to break
the motor in at LOW RPM. Also, at low RPM the heat generated should
be much less and this would be important during a 10 hour run.
You should monitor the temperature of the motor peridically in either
case.
If you want you could use a 3V source (like batteries) to determine
what RPM the motor runs at. Then use your charger and adjust the
current unitl you have the same RPM.
Any other opinions???
