HOBBYWING In Action

The Xrotor F7 FC has an on board pit switch to power the VTX and allow you to turn it on/off from an aux switch on your radio. Mike Chen shows us the quick and easy way to get it setup and working once installed.
Detailed walk through text:
-On the back side of the FC you will need to desolder the currently bridged resistor to the 3.3V pad, then bridge the RX5 pad to the middle VTX-SW pad. Make sure all 3 pads are not connected together.

-Once that is complete you will need to use 3 sets of cli commands to setup the VTX hard pit switch.
-resource serial_rx 5 None
-resource pinio 1 D02
-set pinio_box = 40,255,255,255
-save

First is to free rx5 resource.
Then set pinio 1 to the resource pin
The pinio box is turning on user 1 in the modes tab

This only controls the 10v on the Dji plug output.
