The LEGO company just released a document detailing the complete protocol
used by Power Functions RC receiver.
I host the document on my Power Functions
presentation page.

On page 13 it shows the transmit time slots. Giving each channel a unique
stagger for repeats certainly helps avoid collisions, but Im confused as to why
they have a transmit hold off. If person A is on channel 1, and person B is on
channel 2, they arent going to hit the buttons simultaneously anyway, so I
dont see how having a channel specific hold-off does anything useful at all for
collision avoidance.
