Hey all. Been a very long time since I've been into RC. I own a brand new 5ive. I've got many heat cycles through it. I bought the kill switch along with a Futaba 3PV TX. I cannot get the kill switch to engage when I shut off the transmitter. I have switch 3 to manually activate it. I'm at a total loss. There is not much info out there for this setup aside from 1 26 second video of someone who shows theirs working. Any and all help is greatly appreciated.
