Fred,
The attached picture shows how the button lock push pull control (A700 from ACS)
is installed below the instrument module and under the top of the pilot footwell.
From there the casing makes 270 turn to the left and enters the tunnel through
the right side of the foot well, then goes down vertically, following the
firewall to the flap. A spring is not necessary as the natural aerodynamic
forces tend to pull the flap open. When pulled fully closed however, the aerodynamic
load is very high, so it is critical to build a very rigid and robust flap
(hence the wing shaped profile of my flap). Otherwise the flap flexes under
load and is not effective enough.

What do you think think?

Mmmm....why the difference? The way I read the article it says that TAS is
the critical value. For most pilot this discussion is irrelevant because
the real issue occurs at altitude. However since we all fly here regularly
at over 12k often in mountain turbulence this is very relevant.
Anyway luckily my dynon shows IAS TAS and GS and for now I'll stick with
TAS as the key value.

I seem to recall a discussion on this but I can't find it on the list.
At 12000 ft DA at which I was flying today, the difference is between IAS
and TAS is 20 kts or roughly 20%.
Thanks in advance Will

My very simplistic schoolboy way of looking at it is like this:
VNE - the criteria is the SPEED at which the air molecules pass over the surfaces
but not particularly the amount of them. Hence its the actual speed through
the air (True Air Speed) that is relevant.
ASI actual reading is determined by the pressure of the air molecules in the pitot
tube - which amongst other factors is determined by altitude. For a given
true air speed (actual speed through the air) the higher up you are the less
air molecules there are so the lower the ASI reads. (Or the other way around,
for a given IAS, the higher you climb the greater the TAS will be). For the
same reason the stalling speed is related to IAS and not TAS - amongst other
variables its the VOLUME of air molecules passing over the wing that keeps it
flying, not just the speed of them!
