ours came in, and from what i've read, you have your ground and power pins, and then you have the TTL out put (like what the camera uses)
you would find the pin designations on your RC (the TTL port) and make a custom cable that brings your power and ground to an un used pwm port, and your input pins into the TTL port on the robot
the downside to this ... no camera, because you only have one TTL port
i'm still looking into this, and if i can find a way to hook this up using an analog or digital input instead, that would be great
if you have any more questions or more specific questions specific to your model feel free to PM me
good luck!
