Hmmmm,
If you don’t know the HP that your
engine is developing how would you go about discovering it? Can you
determine HP by climb rate at a known weight?

Let's see, using an isosceles
triangle where the long sides represent the distance from the hinge center to
the TE. Then the similar right triangles formed within the isosceles
triangle would result in the following calc:
2 x sin(.5 x angle) x side = tip movement
or 2 x sin ((10-7)/2) x 11.75" = .61" = chord of the arc of
movement.

My TE to the center of the hinge is
11.75" what would you guess the measurement up from the faired in position
is to get the -10 degrees? You are right there is play on the small tailed
320-360.

One small point. On the ground the
flaps are adjusted and faired in at -7 degrees. In flight the
effective angle is different as the flaps are reflexed further up by air loads
that may well result in -10 degrees. This may be simulated on the
ground by manually lifting the trailing edge of the flap with it at its
electrically powered fully reflexed position and measuring that angle as
the effective flight angle. Don't be timid in lifting the TE.
