I tried using Servo directly and it didn't work. However, using a pulse
output port does work. I got the motors to turn both ways. I should know
this but is the threading preemptive or will I need to put in yields to
make sure the motors keep running?

BTW, when I decompiled the jar, I notice the servos are native calls.
Any chance that the parameters to the PWM call are, or could be, public?

Thanks,
