Hm, we need a document like this on the Bristol:

Here's what Petrovich has to say about control surfcae deflections:

S.E.Va elevator's deflection in RoF is exactly according on the source: 15° down and 37° up
I mean the FM, not graphic animation. May be a bit inaccuracy of 3D animation, but I don't sure about this.
Sincerely,

So perhaps even if it's modeled correct graphically in-game, it could still be wrong in the FM.

Jorri is this what you are looking for? These are same diagrams from the F2b rigging notes 1918 as Windsock Special Bristol Fighter #6 vol.2 These pretty much show the angles of incidence

I thought it was pretty much accepted that the Biff FM wasn't finished on release, reading between the lines of some beta team comments.

There's next to no adverse yaw and no power train effects.

Not exactly, Whiteace. We're looking for a description of the aileron deflection, not the wing's angle of incidence. However, the description of 3/4" aileron droop is good!

The Rise of Flight F.2b has no aileron droop. Here are its ailerons deflected up and down:

Asymmetrical aileron deflection reduces stick forces, but has a penalty of higher roll adverse yaw. It's an effect that is almost completely absent in our F.2b.

Eh..?! You must be flying a different plane then Gav cos I get bags of adverse yaw flying the Brisfit.

That isn't an indication of droop. To check this you need to centralise the aileron and compare the trailing edge of the wing at the aileron and inboard of it.

You are instead 'checking' a combination of 'droop' (which defines a centre-point) and differential throw (which defines the min/max deflection from that point).

I'd suggest that while 3/4 " of droop is important from a control feel point of view, it is not critical for performance, nor obviously visible except when closely scrutinised.

The point of my pictures was more to compare it to our old D.7 ailerons. I wasn't trying to prove the absence of droop with the pictures because that is easy to see by just spawning in the aircraft and inspecting them. ;)
