Hi William,

You might try using the Servo interface directly, rather than the
ContinuousRotationServo facade. This will allow you to experiment with
various pulse widths to see how the ESC responds. Another option is to
use one of the pulse output ports. These have more flexibility in terms
of pulse duration and frequency. To create a pulse train similar to
what the servo ports do, you would have to have a high priority thread
wake up every so often to fire a pulse on the port.
