Been admiring your green Spitfire two-place and wondering what the circular logo - similar to that of Korean Air - represents.

I hope you don't mind a response from me....

The logo is that of the Irish Air Corps. You can get the two seat spit in that specific livery here:

I took that photo of IAC161 at Duxford a couple of years ago. 8-)

She is no longer all-green or in IAC markings. http://www.arc-duxford.co.uk/spitTix.htm

The lady Spitfire driver would by Carolyn Grace and the famous Grace Spitfire restored by her late husband Nick. Tragically Nick was killed in a car crash some years ago but it is thanks to him that we have a number of rare Spits still flying today including the only PR.XI (also my good friend Harry van der Meer was involved in this one)

Going to have to dig out the video now - it's VHS tape and probably a little dusty.

Carolyn Grace has her own website. Lots of information there. http://www.ml407.co.uk/

Downloaded it. Auto-installer. Nice machine. You are in the rear hole. I recommend it for your hangar...

Question for Ozzy: What is the recommended RPM for the engine at sensible cruising speeds. I see the tach goes to 8,000 rpm or so. Surely, this will never happen. The prop is constant-speed, which I assume means it always turns at the same speed regardless of throttle setting once the throttle is above its lowest setting, yes? I always thought turning any such big blade at anything above 2300 or 2400 rpm would send the tips beyond supersonic and thus render the prop ineffective as a propulsion device...

Sounds like you need the pilot's notes.

For Spitfire IX, XI, XVI pilot's notes:

Just like this!

Page 9 and 20 for engine limitations and suggested settings.

Quite tasty info. Those engines must have been very finely machined and balanced to swing a 12-foot prop at 3,000 rpm. Fabulous work...
