Time to hack it? Afaik, it has an ultrasonic range finder that it uses to maintain a safe distance to the ground (this could be tested by launching it from the top of a roof and observing its behavior). After that it's just a matter of finding the right pin and giving the onboard controller the right PWM signal. :)

Of course the radio might be too weak for any sort of serious teleoperation.
