I have sympathy for your difficulties.
Again, the suggestion is one of inaccuracies in the programming of the temperature effects in the game as against engine power and airspeed produced within the game.

The unique flying qualities of any aircraft are totally irrelevant to this specific issue.

Nor was I necessarily intending to have a discussion with anyone. My intention was to inform the readers of the forum of an observation made in one specific test of the game's 'temperature effects' setting relating to one specific aeroplane, and to suggest that others conduct similar tests in order to verify my findings or otherwise in other aircraft within the game.

Please feel free to test this yourself with any aircraft of your choice within the game and report your findings accordingly.

Control and stability remember?, you raised exactly this point yourself in 'that' thread, remember?
Stick force per G is a characteristic affected by stability, you spent a very long time telling us how the Spitfire instability is what made it so tricky to fly with it's 'low' stick force per G, you can't just keep changing your arguments like that.
the fact the Hurricane could turn well was more to do with it's fat wing which was much less critical at low speed handling.

Please provide a link to what you think I said. Don't do it in this thread. You can just PM me. In all probability, you are confused and we can leave it out of this thread. If you are right, I will be glad to post it in another thread.

You mean the issue of "British FM killing the fun of the game for allied pilots"?

Did a quick test with temp effects off and got similar results. The real life Spitfire II PNs: The Spitfire II could show up to 125° coolant temp for climbing for 1 hour, and 90° for oil.

135° coolant and 105° oil for 5 minutes emergency boost



And the Pilot's Notes General on engine handling - issued with all Pilot's Notes, and always used in conjunction with them:



Note on climb speed and how engine temperature could be improved by adopting a higher climbing speed, plus radiator settings:

On the related note, what if its the oil pressure dropping during negative G manouvers and causing the engine to seize? Oil pumps are driven by the engine, so pressure may fall below minimum - lubrication is gone, but the engine is still revving as the propeller still drives the engine.

AFAIK this was a problem with constant speed propellers as well, since they were hydraulically operated on many aircraft and could cause the engine to overrev.

I'll give it a check.

Which type?

I recently read in a RR Heritage book on the Merlin that rolling in the Hurricane eventually caused lubrication problems and rough running but not to the point of seizure. RR had to test this and ran tests of 150 continuous aileron rolls before any of these signs appeared, but no seizure. IIRC the pilot doing this was the same one who managed that .92 mach Spitfire dive @ FAE (major parts fell off during the dive and the engine oversped to something like 4200rpm, but he still landed OK)

These will all rob power from an engine. So while the engine may run rough or work with oil temperatures 125 degrees, it will not make more power than a fresh engine that has not been abused or is running rough.

The Dev's should publish the procedures for proper operation and if those instructions are followed, the power production is the same as when "temperature effects off".

Is there an official Operating Notes for the game? The only ones I am aware of are from players.

I think its hard to believe that the Devs would release a patch that fooks up the FM's and if they did not release a quick hot fix by now even if it meant rolling back the FM to pre beta state so I can understand the angle Crumpp is coming from here..

The Devas have a wealth of info in regards to these FM's and have accumulated this over many years....I suggest they release what they see as proper operating instructions for these aircraft, what have they wrote into the FM that they see as proper operation, that would be interesting to see
