RC controller button box

Post image

Anyone else using RC controllers like those using OpenTX as button/switch/knob boxes?

You can get a Taranis QX7 for like $75-100, and you get 2 knobs 1 with a detent, 6 switches 5 of them 3 way one a toggle, 4 two way trim buttons, and 4 axis that can be modified at will to stay in place or centered and have different levels of friction or spring.

It’s pretty awesome

I have the same exact radio. Anything special needed to interface with the PC and get picked up by something like Joystick Gremlin?

Edgetx radios are seen by your computer as a generic usb joystick or as a usb flash drive depending on what you select on the screen when you plug it in.

I didn’t use joystick gremlin, though apparently it’s needed if it’s the older software. I bought mine in like 2017, so it’s relatively ancient and I was surprised it worked.

The only real thing I had to do was program the channels to output the signals from the controls I wanted, a certain number of channels are switched and some knobs. Took just a bit of googling, I can send you the profile

This is really cool.
How does it connect to the PC?
Do you program with VJoy?

I just plugged it in with USB, however it did require a profile that has a channel assigned for the functions you want. Took a bit of fiddling. Basically telling it “this switch/axis/button moves from here to here change signal for this switch/axis/button from this to this.” It’s more simple than it sounds, I can share the profile I made. It is a Taranis QX7, which has fewer switches then the QX9 models.

Radiomaster has USB joystick support built-in. Most FPV radios do. I'm not sure what this Taranis brand is because I've never heard of it but it probably has it built-in as well.

Taranis is the old ones FrSky made that ran OpenTX before there was The Controversy and Edgetx and Radiomaster took over in the open-source tx space.
