Would it be possible to .. send the data to generated from MegaServo or that to be sent to one of the servo controller boards from Polulu, to an RF module or maybe an Xbee module. Then to decode this data at the other end to control the Servos?
Like this
Arduino -> (signal for polulu board) -> xbee -----------
--------------- xbee -> arduino -> polulu board -> servos
Easier R/C ?
