Unless you have -actually flown- a spit, you're just interpreting someone else interpretation. Your opinion is in no way based on fact. Yet you demand a change when you have no idea what the accepted standard actually is.

I don't like it either, I wish I had flown a real Spitfire or had some nugget of data that gave us the designed Spitfire trim speed, however sometimes the only way to find an answer is to extrapolate from various sources, and make best guesses from interpretation.

TD have made a decision about the aileron neutral trim speed that they interpreted from the manual. Nowhere, nowhere, does it say in that manual, that the max economical cruise speed and rpm is the setting at which the a.c is trimmed. THEY INTERPRETED AND INFERRED IT.

On that note, I'm trying to correct it, based on EDUCATED and INFORMED analysis and some RESEARCH. I can't give you a figure but I'm trying to find it and in the meantime, demonstrate the questionable logic of having an a/c - any a/c - trimmed for such a low relative speed in it's performance envelope.
