Thanks for the ideas!

I do have a boxed and sealed fresh cougar in the basement that I only ever opened once to verify a part worked a certain way, that I bought on sale when I got my first cougar. I figured the stick was mostly perfect save for the gimbals, and may need a backup some day in the future, so I could always break out that throttle, but I'd rather see if I can get this brake working on its own.

Are those vipergear hall sensors still for sale? I never got a hall for the throttle, but I imagine it'd be pretty nifty to have.
