'Peril looks at the Hurricane tested data posted above and scratches his head'. You guys interested in what 'actually' happened in the case of the Hurricane or what mathematically should have happened but didn't?

So, to round that up for you, the plane should trim neutral in roll @ ~130mph, seems you missed the answer or at least the point to the question? (not 42 in this case)

It's really not that simple, since we don't know very much about the test aeroplane, the power setting (i.e. manifold pressure & rpm) used or the altitude at which the test was carried out.

In fact, for all we know at this point, it could have been a Hurricane II with a Merlin XX, metal wings & ailerons at one extreme, or an early Hurricane I with a Merlin II or III, wooden wings and fabric covered ailerons at the other, and climb power could mean anything from 2600 rpm, +6¼ psi (Merlin II or III) to 2850 rpm +9 psi (Merlin XX; which also has a 0.42 reduction gear instead of 0.477 for the Merlin II & III).
