In the process of switching out a bunch of old frsky stuff. ### ⭐ Receiver came defective *by M***T on August 23, 2022* Checked wiring 3 or 4 times before powering up and it instantly went up in smoke, never had a receiver do this before. Checked the board with an ohm meter and sure enough power was shorted to ground somewhere on the circuit board.
