I Want my 4.09 Spit FM's back.........

[swiss]

That's my problem - I DO NOT THINK IT IS CORRECT FOR ANY AIRCRAFT TO BE TRIMMED FOR THE CLIMB. Logically, it seems common sense to me to put the trim neutral state of any flying surface, aileron, elevator, rudder, whatever in the approximate middle of that a/cs speed range or at least at around the combat cruise setting, since then the out-trim-forces are balanced at opposite ends of the speed-range

Here's the problem, you "think".
That means you don't "know".

Is suggest you bring proof for your theories. Why drop a line to Flying heritage?
Or, maybe your even able to contact a ret. RAF testpilot.

Defending your point of view is much easier if you have something to show which actually backs ups your argument.


Edit:

Nowhere does he say the Spitfire suffered from aileron reversal.

Swiss, you and I don't see eye to eye on much, I know. Regarding the think and feeling, please re-read my posts. These sentiments are not based on over romanticised History Channel thinking, but 20 years of learning all I can about Spitfires, with plenty of airtime, flight training, and research thrown in.

To quote your wiki link:

...the possibility that pilots would encounter aileron reversal increased...The original wing design had a theoretical aileron reversal speed

There is no documented case of Spitfire aileron reversal. This was a rare case of an a/c designer pre-empting a potential problem, NOT reacting to an existing one.

Thanks Swiss, I'll look into this.

Also, to clarify, I don't want a return to the 4.09 Spitfire FMs; I quite like the new stall/energy characteristics.

The only issue I have is with the lateral trim.

Then that should be the focus of any further argument...and once again, thanks for your input!

Actually, I think TD have done an excellent job in making the Spits lighter in the azimuthal axis, Mk Vs now float off the runway at 100mph very nicely, and the stall is less sharp - as it should be with that shape of wing.

Good to hear from you Fen, I've never forgotten that Sv109s desert map when you went off and downed a gaggle of 5 109s on your own...
