Making your Switches work 🍕

To actually make the switch work, you will need to bind the Radiomaster TX16S to your quad's receiver. After binding the Radiomaster TX16S to your FPV quad, you will need to set up the switches in the flight controller software. In this case, we will be using Betaflight 4.4.

Step 14: Open Betaflight 4.4 and connect your FPV drone to the computer.

Step 15: Select the "Configuration" tab.

Step 16: Scroll down to the "Arming" section.

Step 17: Select the arm switch you added in the EdgeTx Companion software.

Step 18: Repeat these steps for each switch you added.

Step 19: After setting up all the switches, click on the "Save and Reboot" button to save the changes to the flight controller and restart it.

Checking in Betaflight which switch is on what AUX Channel

You need to check which AUX your switch is on in the Receiver Tab. When you move a switch you should see the colored bars move back and forth. If your receiver is NOT connected to the radio you might not see switches moving. Also check to see if the sticks are moving. If nothing is moving you need to possibly change activate the right Serial Rx in the PORTS tab. Once you see the switches moving you can then setup your MODES to the switch by selecting the matching AUX you see moving in the receiver tab. Sometimes I go back and forth from the Receiver Tab to the Modes tab to make sure it’s working properly.

If the switch moves the wrong way you can switch the direction of the switch in the radio.

Reversing a Switch Direction

Change switch direction in the radio by going to the INPUTS menu in the model menu. Next choose EDIT. Once inside the AUX 5 ; which is usually what spot I put my ARM switch on ; you can then go to WEIGHT. Reverse the direction to -100 or +100. This is essentially the same way you reverse a servo in the radio. In this instance we are reversing the switch direction to work properly in Betaflight. Only do this step if you need to. - Don't forget to click SAVE in Betaflight when you make changes,

Once the flight controller has restarted, you should be able to see the switch working in Betaflight 4.4. To verify this, go to the "Receiver" tab and check if the switch position is changing when you move the physical switch on the Radiomaster TX16S.

Setting up a switch for a quad in the Radiomaster TX16s is an easy process that can be done using EdgeTx Companion.
