Default limit of trim = limit of travel?

your questions dont have that much depth btw.
just a lot of misunderstood aerodynamics.


Naysaying is the mark of a troll wihen no facts are given to back it
up.


Cheers


accusing someone who disagrees with you of being a troll is so lame.


ok lets get this in proper perspective.


the average GA tailplane has a span of about 8ft.
the trim tab sits on only one side and it is about a foot span and
maybe 2 inches chord.


Go and measure an Arrow or 177. Even a 172 has a bigger trim tab than
that. BUT you still don't understand the point.


just considering the tailplane chord through the trim tab for the

time
being. you are looking at a chord of about 2 ft. *
wound to it's full extent it would have maybe 5% effective change in
the aerofoil characteristics. bear in mind that it lives down near

the
trailing edge where the contribution to lift is minimal.


With this last statement I can see there is absolutely no point to
discussing this with you as you don't know how an airfoil works.


He does understand actually. your own understanding is extremely flawed.

Sheesh you say good bye a lot.- Hide quoted text -

You have me confused with someone else.
