Pretty simple really. Air radios go from 1ms to 2ms pulse width for the throttle. Pistol radios go from 1.5ms to 2ms pulse-widths for throttle (1ms to 1.5ms is for brake/reverse). The device translates the starting 1.5ms in a PG radio to 1ms pulses and shifts the pulse width to be linearly variable up to the 2ms max value.

The concept is simple. Programming and packaging is a tad more difficult. The device uses a PIC (programmable interrupt controller) which contains some actual code that does all the work. Since the signal wire is not even close to a high power signal, the circuit doesn't need any output buffers or anything, so it is all contained on that one IC.
