The maximum useable deflection angle depends on the relative chord of the control surface. A good first-order value is ±20° for a 20% chord. With increasing chord, the deflection range will become smaller, like ±15° for a 30% flap. With ailerons, things are a bit different because they are part of a lifting surface. This gives them some pre-loading so the ...

This is thinking a little "outside the box", but one thing you could do is use to the internet to locate some manuals for some ready-to-fly radio-controlled model airplanes such as those produced by HobbyZone, etc. The manuals will typically list "low rates" and "high rates" for each surface. The "low rates" have to provide the minimum control throw that ...
