Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

The data sheet is on the link that you posted.
I would say that you are better off not using it, it seems to be designed specially for radio controlled cars.
you should be able to control it in exactly the same ways as a servo.sounds like a good solution to me.
That's what I tried. I sent pulses every 20ms and by varying the length of the pulses I expected thevoltage on the output wires to change. But so far no success.
if you hook up a servo instead, the servo works, right? if the servo works, the ESC should . . .unless there is a reason it was in the attic Wink
make sure you have teh ground, +, and signal wires correct, cause diferent servos/esc have diferent plugs
I'm sure the ESC is not broken since I tested it with the original receiver and transmitter.
Is this a special receiver? Do servos work with this receiver?
You aren't doing something right here . . .
You said:servo works in receiverservo works in arduinoESC works in receiverESC doesnt work in arduino?!are you sure you have grounds common on the ardiuno? meaning, is the ground on the ESC also connected to the ground on the arduino?
The only remaining problem is that I get 0V or the maximum voltage (+/- 7.5V) and nothing in between, so when I fire lets say 1600 us pulses I still get the full +7.5V... some more testing to do...
Actually this isn't a problem, this is how PWM works.Voltage stays the same, its the frequency and wavelength that change. Hook it up to an oscope and you will see how it changes.When you hook the motor up, you will see how the PWM changes the motor speed.
