Someone else (Robin I think) mentioned that way back when I first talked
about getting them. The first thing I did when the platform was built, was
run the platform up and down the lawn measuring the current for about 1hr.
The motors were quite warm after that but not hot.

If they do experience problems down the line at least I can replace them
cheaply or even select another motor, but I needed to get started and the
choice of motor was stopping me from progressing at all.
