You can create models using OpenTX/EdgeTX Companion installed on your PC. First, read model information from radio, then create and edit them on OpenTX/EdgeTX Companion, and write it back to the radio. The model information for up to 60 aircrafts stored in the radio is managed as one ".otx" format binary file on PC. You can manage by creating multiple ".otx" format files on your computer and transferring them to the radio as needed. This way, an infinite number of model information can be used in one radio.

If you select [File]-[New] from the menu here, you can create a completely new ".otx" format file. If you select [File]-[Open], you can read ".otx" format file stored in your computer.

EdgeTX, which has a faster development pace than OpenTX, may already support even radios that OpenTX does not support. If you are using OpenTX, you may consider migrating to EdgeTX.
If you see this error even though your radio is supported by OpenTX/EdgeTX Companion, the model information file stored in the radio may be corrupted. It may be solved by initializing or replacing microSD card or updating the firmware of the radio.

You can use icons to the right of this icon to perform operations such as "delete", "cut", "copy", "paste", and "insert" the model. You can also copy an already created model and edit a part of it.
On PC: Setup screen settings


First, click "Setup" tab. This is the screen for basic model settings. All you need to enter on this screen is the model name and transmission protocol settings. Enter any model name in "Model" field. You can use alphanumericals, white spaces, and hyphens in the model name.
For details on these all setting items, see MODEL SETUP setting items explanation .

Drone to be bound this time uses "D16" type in Frsky protocol. Select "DIY Multiprotocol Module" in "Multi Radio Protocol" field. Select "FrSky" in "Multi Radio Protocol" field and "D16" in "Sub Type" field. No other changes are required.
This setting screen changes depending on the protocol selected. Depending on the protocol, it may be necessary to set other items as well. Check website or instruction manual of FC board or receiver board.
For information on how to set the communication protocol when using the ExpressLRS (ELRS) protocol, see How to set up ExpressLRS transmitter .


Depending on communication protocol selected, "Failsafe mode" field on this screen allows you to specify how the drone behaves when communication between radio and drone is lost. See Failsafe settings for details.

On PC: Input screen settings

First four channels are already assigned Aileron, Elevator, Throttle, Rudder in that order. This allocation order is determined by specifying "Default Channel Order" field on [Settings]-[Settings] menu screen. Since it is a virtual channel, it can be assigned in any order. If this order does not match the aircraft you are binding to, change it on next Mixes screen.

In the "Source" field, select SG (Switch G) that will be the input device. You can give this virtual channel a name in "Input name" field. Since Arm is assigned to SG this time, I named it "Arm". You can leave the name blank.
Similarly, assign SA, SD, SH to virtual channels 6-8. Since it is a virtual channel, it can be assigned in any order.
For details on these all setting items, see MODEL INPUTS setting items explanation .
If you simply assign one switch to one channel, you can register it directly in "Source" field of next Mixes screen without registering the switch on this Input screen.


On PC: Mixes screen settings

First four channels are already assigned Aileron, Elevator, Throttle, Rudder in that order.

In "Source" field, select virtual channel [I5]. This time, "I5" is named "Arm", so select [I5:Arm].
When we defined virtual channels, we specified the same number as the physical channel, so simply set [I5:Arm] for CH5, [I6:Mod] for CH6, [I7:Flp] for CH7.
For details on these all setting items, see MODEL MIXES setting items explanation .
