How to use an iPhone to Fly R/C Airplanes and Helicopters

<i>Finally, you may ask how the servos are being driven. Well, routers are used to send bits of information down a series of twisted pair wires usually. Guess what it takes to send packeted information? An IC that would work really well as a PWM! I did some haxoring around on this, and read what other nerds had done on the internet, and the next think you know I have a servo with a Cat5E plug on the end of it.</i><p>I'd love a <i>lot</i> more detail about this "then a miracle occurred" stage of the build. Drive a servo with an ethernet port?! Anyone know how to do this? That sounds crazy cool.

Way Cool!<p>I did a hack a few years ago that made a PSX Dualshock pretend to be a buddy box. A PIC polled the joypad, then fed a PPM stream into a Multiplex 3030 xmtr. Having a centre-sprung throttle was neat - but other than that - it was not the best control experience ever.<p>From the eminent comfort of this armchair: If I was going to do this - I would have left the router on the ground and used a couple of XBee modules, with a micro (PIC, AVR) airborne to drive servos (4017 to spread 1 pwm pin to the servos)
