I was setting up the airbrake function on my Futaba 7cap transmiter and have come up with a problem. The manual, on page 74 states that the airbrake may be triggered by the throttle stick position. It then refers you to page 52 where no reference to assigning it to the throttle stick is made. In tweaking with the radio it appears that this function is exclusively assigned to the "g" switch. Is it possible? Is the manual in error, or am I missing something?
