I can relate to you Chris in that we lost big time, some of our senses when the TBI "sheering" occurred, and our inner ears took a beating,
but in my case I noticed, that as I recovered, my tactile senses and my vision got much better, is it the same for you?
If your hands are "sensitive" enough now, and I know they are, to twist a wrench, play your guitar, type your great words, and swing your golf club, you will have no trouble gaining back that muscle memory for the control bar, especially if you can get some time in with your Predator in a stiff breeze, maybe tethered, and just, "dance with it".
I remember in 1980 when I heard Johns wires "singing" as he did 6 loops over my house.
What an awesome glider that Predator,

and John, well... .
I think you could write a guitar piece about these old, but new, experiences,
and your Predator is a finely tuned machine isn't it?
Maybe an A-432 tuning...ha..
Stay safe out there.
