Thanks for the tests and very useful replies chaps

My comments -
Keith - AllanL is correct, the Cirrus II is rated at 85 h.p. not the 84 h.p. in my aircraft.cfg ( my dodgy engine ) Thanks Allan.
I think this shot possibly answers the mixture question -

It's from a Widgeon restoration project and although not definitive is the best I've got, so ...
Your comment about the top aileron rods - is that in the V.C. or exterior, wing out or folded - I've had quite a problem with them.
Yes. I'm working on the gauges, as you know.
JohnD -
Sorry about the P3D limitations - I don't have that installed so can't check but I think it's always going to be difficult reconciling
FS9, FSX and P3D and I want to model for the FS9'ers still out there. BTW - elf&safety note - make sure you stand outside the aircaft before
attempting to fold the wings

.
Mike - yes, the engine rockers move in the correct sequence but- a waste of my time because the Flightsim frames per second waggon-wheel effect mucks it all up.
Brian - Pop-up overlaps ? something I always forget because they can be dragged to any part of the screen - but it will be done.
Yes - the mags switches have an associated tool-tip in the 2D screen (for FS9'ers) but that's no use to others so I've now added one
to the 3D switches model in the VC .
Thanks again all - just a bit of tidying to do and the it will be released onto the unsuspecting world.
Cheers
