Spitfire Rads - How closed do you go?

[Trooper117]

Set to normal once in cruise.. close rad if it starts to drop out of normal operating temp..
Just monitor temps really.

+1

Fully open for take-off, then once airspeed, pitch and boost are set, and the a/c trimmed for the climb at 160 IAS, I reduce to halfway (or about 8 or nine clicks if you use buttons), check trim again and pretty much leave it there.

I close it fully when diving with power off, then open up to normal. As the other chaps have said, keep glancing at the temps. Prolonged fine pitch/high revs sends your oil temp soaring, but a few seconds of coarse pitch brings it down again really quickly.

I very rarely boost the engine beyond +5 unless in combat, and open rad fully when I do.

same with Dutch

Thanks chaps, very useful indeed. What is 'normal' setting though? Was there such a setting in the real world or are we talking about simply half open? Will check tonight, but is there any cockpit indication (other than the position of the 'handbrake') of where the rad is?

Thanks

Heh, heh. Normal for me is halfway. I read somewhere that pilots used to line the 'handbrake' up with the corner of something on the cockpit wall, but I forget where I saw this and also what it was. But yes, 'halfway' is 'normal' for me, there's no cockpit indicator as such.

This is one of the reasons I prefer to fly the Hurri, as it has an indicator - which is a bit strange because I'm a typical Spitfire nut.

Half way for me as well
