For all the advantages that switch arming has over stick arming, there is one big disadvantage: you can easily bump the switch and arm the copter unintentionally. This video shows you how to set up a "sticky" arming switch on your Taranis. A "sticky" arming switch means that you hold the momentary switch for a half second or so to arm, but disarm instanatly with a throw of the non-momentary switch. This means that you can't arm accidentally, but you can still instantly disarm if needed during a crash. This really is the best of both worlds, and should completely eliminate the need for anyone to ever stick arm. (That controversial statement is intentionally placed to stir up trouble. Please ignore it.)
