I have a Logitech extreme 3D joystick which works fine. The thing is I’m a armchair laptop simmer and I really hate having a wire connected to it all the time. I tried using a wireless Xbox game controller but as I’m not a gamer, I just can’t get the hang of it. What I’d really like is a Bluetooth or wireless joystick. Do any exist?
Nope.
And other than the convenience of no wires, why would you want it? It’s gonna take a gobsmack amount of batteries and could be interfered with by your wifi network, microwaves, cell signal… especially in flight sims you don’t want any inherent latency that’s created by wireless technology
That’s why gamers tend to prefer their mouse to have a tail 
Almost every high end gaming mouse has a cable since wireless often can’t transmit the full resolution
except he’s talking about a wireless joystick.
I think the turtlebeach joystick they just put out specifically for console users is even wired.
yknow i bet with a little engineering magic you could turn a wired joystick wireless. I’m not really making it as a suggestion, just really pondering the feasibility. Comes back to “Just because you can doesn’t mean you should” though
Yes, I’ve got a Saitek Cyborg EVO wireless joystick stored away. I’ve not used it for years but it worked okay. And the battery life was fine.

Here try here. I didnt actually read it but thats what came up in search, maybe this can help you out.
You would think there would be a market for a wireless (or wired) joystick that was a little smaller and portable since MSFS 2020 came out. But I guess not. Back in the day smaller joysticks were a dime a dozen. Just give me a smaller twist joystick with a few buttons and thrust.
