happens when the car descends the

The resistance is higher and the
underlying current and power are
lower — not by much but it is
measurable, nevertheless. I didn’t
have time to run anymore tests with
steeper ramps, but I’m sure that
equivalent results will prove that even
more power is needed to climb
them.

Adapting Telematics
to Other Model Cars
While the Hydrocar is a great
example of what can be done with
remotely monitoring live data, the
telematics boards can be adapted to
any number of model cars that you
or your kids have lying around
