As shown in the vid (about 1mi in) It’s activated by holding roll right and pitch back.

Sounds like you’re trying to arm the quad using the wrong stick on the transmitter.

I can’t get the Lost Copter alarm to sound using the stick combination. Was it replaced in 3.4.4 with the Ch.7 Option: Lost Copter Sound?
That works, but is there anyway to turn off the sound once its triggered?
