If you take any one of your assembled models and draw a plan of the wing
and stab, then whatever you do to the MS and tailboom should not change
the relationship between the wing and stab. So if you turn the
motorstick to the left then you need to do something to the tailboom so
that the stab position relative to the wing doesn't change. This will
probably also mean repositioning the tissue tubes on the stab. If you
use a separate rudder instead of raised stab tips then you also need to
keep the rudder in its original position relative to the wing.
There are probably any number of other ways to accomplish the same thing
- that's just the way I've been doing it.
