Here're a couple of updates.  Well, one's an update - the tsr2 and this now
has reasonable wing and hstab values.  The roll rate was very high and I
figured that as it was going to be a hack anyway, due to the all moving
tailplanes, I just made them very ineffective and linked them top the
tailplanes in the model file.  I think I may have over factored them a bit
too much but it's interesting watch them in chase view.  If the autopilot
roll-out-deg is dropped to about two it'll start oscillating, and from behind
it looks like it's paddling:)

representation of the aircraft. Having said that, the
numbers, where I could find them, roughly match those of
the original aircraft. Lee Elliott.
The ailerons are a hack on this fdm - the real aircraft
use all moving tail planes for roll and this model had a
very high roll rate so they've been made relatively
ineffective and in the model/anim file the aileron surface
positions actually operate on the tailplanes.
