Hmm. I've rigged and derigged DG1000 a number of times and never had
to do anything special with the airbrake lever and the brakes stay
locked with the wing off the plane so, yeah, the overcenter lock must
be inside each wing. Never thought about that.

Both airbrakes and ailerons are definitely driven (at least initially)
by torque tubes with self-aligning V-shaped slots.
