I'm starting to get arthritis in my hands though and it hurts pretty bad sometimes so I'd really like to try something that doesn't make me hold on the radio *and* fly. Maybe I'll just get me a ''scooter'' and build a shelf on that to lay my radio on and then I won't have to worry about it.
We have a club member who can only walk a few steps, and he has sensitivity and dexterity issues in his hands. He works with one of our instructors who helps with starting and getting the plane to the taxiway. Like me he flies on a buddy box because the issues with his hands could be a safety issue without it. He uses a scooter and shelf almost exactly as you described. If his plane dies on the runway he drives out and hooks a line to it and tows it back.
If we worried about being different than the other pilots we wouldn't be able to be in the hobby. The fact that scooters, trays, etc are available gives us the opportunity do do something we enjoy.
