Seriously if you measure the vertical trailing edge distance below the
wing tip on the ground for 6, 12, and 18 degrees and look at it from the
cockpit you will then find it fairly easy to judge in flight.

From memory I think it was 13" pivot point to trailing edge so if that
is correct then a bit of trig will also do it. sin(18)= y/13 or
13 sin(18 degrees) = 13 x .31 = 4 inches down

I do have to push to get reflex. One interesting thing I have noticed
is that if I stop the flap handle from going into a detent and let the
flaps float where they want to in cruise they sit right at neutral with
no force required on my part. Ken, It's good to hear you have achieved
18* in flight. I'll keep working on it. How did you measure your in
flight angles?
