....the rudders deflect "out". I was going to use a brace like these, just one
on each inside vertical stabilizer....to shore up the fins. They will get a lot of
stress if used as airbrakes.

Even with these on the Ultra Stick....the rudder could deflect 90 degrees, if
nothing was in the way.

The fins just glue into a slot, they could easily be bumped and damaged in
transport.
