I'd also be interested to see what can be done to
modify the old version of Precise Flight Speedbrakes.
I have the brake assemblies but not the rest of the
system. So far the folks at Precise Flight haven't
been very helpful. I may just improvise my own set-up
still using the cable and a motor/drum that would do a
180 deg index with incremental control for degree of
deployment.
