We know we will be adding more power than what the plane
was designed for and knowing the horizonal of the original
TwinStar is a weak point on the plane we have modified it to
make it stronger and more effective..

The pink line shows where the original hinge line was.. Just
making the elevator a larger surface does not really do a lot..
But to make it larger while reducing the horizonal area by same
amount makes elevator more effective..

When the hinge line was cut in the trailing edge was replaced
with dense balsa.. The forward area of the horizonal also has
had dense balsa cut in to strenghten it so that it does not fold
or flutter..

Robart pin hinges were used to secure elevator to horizonal and
to allow elevator to deflect up or down to about 50 degrees..
Will it ever see a 50 degree deflection,, I highly doubt it..
