[NSRCA-discussion] Flying stab travel

[John Ferrell]

I am not an expert but I do know it is not a trivial decision to design 
a stabilator. An elevator with a hinge line is naturally rigid. Side to 
side coupling must compromise the elevator function or the rudder 
function. It is a likely place to encounter flutter. Checkout 
https://en.wikipedia.org/wiki/Stabilator

For just plain cool factor in a pattern plane a servo on each stab half 
will let you twist the tail in flight with a weight penalty.

In the real world I recommend a V-Tail Bonanza.

I would stay tried and true on my Senior Project because the students 
grades are just too important to risk.
