It's something to be seen. A fellow racer at the tracks has lost his left arm at the elbow. Watching him drive with a dx3r radio is simply well you just have to see it. Resting the back of the radio against his chest and elbow,he then uses his ..right middle finger to throttle then his thumb and pointer finger (on the same hand) do the steering.
My question is could a radio company make a radio that the steering wheel pushes in for throttle, then pull out for brakes. In a sence he could then just grip the wheel comfortably and apply throttle and brake with a push or pull, instead of the funky three finger setup.
Anybody out there have any other suggestions.

The best thing that I can think of is to use a single stick or double stick radio that is approved for surface use. Put both controls on one stick and use a transmitter tray like some of the airplane fliers do.

not a bad suggestion and these days almost anything can be done by the "basement inventor......if you took it to a manufacture they would probibly tell ya thier was no market for something like that, been in the hobby 40 yrs and never seen anything close to that configuration, not saying it couldnt be done, just specialized to fit the persons needs and can probibly be custom made

I learned out how to drive RCs with one hand. Granted it was my left hand which obviously would be a problem here and my reasons were because it was freezing outside and/or I wanted to smoke at the same time and that was the only way to keep my hands warm / lungs filled.

There are plenty of radios that have a right handed feature on them. I used my standard trigger finger and thumb to steer. I sometimes still do at the track. Always gets a funny look.

Anyway, anything is possible. I wouldn't know how to do it really but I would bet Monster Mike or the Jang could figure it out. Maybe shoot em an email.

There's a guy were we race that lost his right arm at the elbow, uses his stump to steer the radio wheel, absolutely amazing.He does all of his own work, paints his own car bodies, builds his own kits. I was floored when i first saw him race, he tq'ed and took first in both pro stock truck and buggy. And i thought it was hard to race with both hands...

i know a guy who uses his 3pk with one hand he wheels everyone.

I’ve always thought this is one of the coolest aspects of our little hobby, that so many with various challenges can still come out and have a good time. So many examples over the years come to mind, and generally some of the most positive and uplifting people too. So many great lessons for us all, especially our younger enthusiasts.

Back on the question, it’s certainly possible to rig up a wheel radio like asked, essentially just need to combine the second pot and rig up a travel mechanism. This is the kind of project I could really enjoy working on if I had the time.

Practically though seems like the simplest approach is the stick radio mentioned. Might be more stable mechanically too, at least without some good design and support construction for a wheel approach. Perhaps best to start with a surface version radio, aren’t the air radios set up differently in regards to spring tension, neutral-brake, etc? I know this tends to be thought of as somehow inferior in the US, but it never seemed to hold back Masami or any other number of top racers around the world that use sticks.

Thanks for all the reply's guys. He does great now so maybe something new would give him trouble. This is one of the greatest features of rc-tech that all the years of experience and things seen by so many I was just throwing it out there to see what others thought.

I like the idea of using a stick TX and binding the steering + throttle on the right stick...

If it were me I might try a left handed grip & put an extension on the wheel like a lever that he can move with the stub.

The most effective (but full custom) is to put a trigger on the face of the wheel that can be twisted to steer. A cup can be configured to help hold back of the of the radio...

Extending the leads & relocating the throttle trigger may not be at all hard... just gluing the grip & trigger to the wheel is the hard part. (not hard at all)

There is one racer in my area who had a foot pedal connected to his radio, so he uses the stump to hold the radio, normal steering, and foot pedal throttle.
