Misc. Can I transmit from my power wheelchair controller?

[MSMatt]

Hi, new member so apologies if I'm posting in the wrong place.
I was really into rc cars and trucks when I was younger but life got in the way and it's been 20 years since I had my own. But now my son is 10 so he's moving out of the toy category and I can get back to it.
However life really did get in the way and now I've got multiple sclerosis. I keep getting worse symptoms at varying speeds so who knows how I'll be in a year but for now I'm in an electric wheelchair and my hands don't work. My arms are very relatively ok so I can still use my hands to push against things but obviously any normal transmitter is out.
Im sure I could find a specialised one for people with disabilities but honestly money is an issue so I haven't even looked and my arms are so weak and my motor skills so poor that I would probably still struggle.
However I'm a demon when it comes to controlling my wheelchair. I have a golf ball on the joy stick and would take on lewis or max when I'm I'm the zone!
My question is can I use my wheelchair joystick to control an rc car?
I used to be as good with a soldering iron as I was with a welder (probably not as good as I thought) but obviously now I'm useless. My dad was an engineer all of his life so he's pretty handy but old and busy af so I wouldn't want too much work but is there anything out there that could be potentially adapted... or has some clever clogs already done it??
I'll attach a photo of my wheelchair control so you know what I mean.
Thanks to anyone who takes the time

It's probably be easier to adapt a 2-3 channel radio made for ground RC use to suit your needs than to design something that interfaces a wheelchair's joystick to the radio. It'd be relatively easy to find someone to create a ball that would screw onto the radio joystick, then you'd only need to concern yourself with increasing the spring tension you'd need to help maintain some muscle control.

If you tried it the way I believe you are thinking, then you have the additional work of adapting electronics over that were not made for that type of control that an RC radio has... ie proportional controls like all RC radios and receivers are made to work with. I wouldn't be surprised if that also would require designing some electronics as well as programming them so they'd work properly.

I'd suggest talking to a wheelchair tech or specialist about it. There are probably few in RC hobby that have attempted this but no doubt someone in the wheelchair industry has in order to do something just like you are thinking about.

Yeah thanks very much. That's almost the exact same conclusion I came to.
It would be cool though!
