1. TX‐failsafe feature: This method sets the failsafe on the FASST transmitter and has priority (works on
channel 3 only under FASST 7ch modeor on multiple‐channels
 under FASST multi‐channel mode) while
thereceiverison,justlikeFUTABAreceivers(onlyavailableonFASSTairsystem).
