Spitfire & Hurricane flight model & engine performance thread. (1.09 patch)

[MadTommy]

I thought we could do with a thread to discuss the changes & way things work now with the 1.09 patch. I've copied some peoples observations for other threads.

PLEASE POST YOUR OBSERVATIONS

I'll start with the pilot notes for Merlin XII engine as a reference. (thanks to ATAG_Snapper)

_________________________________

I tried a climb in the Spit2a and had these results:

Climbing at 7lb boost, 2,850rpm, IAS ~155, rad half open.
Temp gauges all within limits when at 17,000ft my rpm started fluctuating wildly, causing cockpit shake. I was unable to control my rpm.
Oil = 85, Water = 100.

Only way i could stop the shaking was sub 2,100 rpm & sub 4 lb boost.. managed to get to 19,000ft but could not maintain a climb..

These observations and been confirmed by others.

Sea level run: 270 IAS 9 lbs/3000/35% rad
280 IAS 11 lbs/3000/35% rad

Highest I could get 1a100 to was 22,500ft.
Highest I could get 2a to was 19k ft.

Hurricane takes about 20 minutes to start. Needs water temp at 45 degrees. (can they not just spawn already warmed up?)

I've noticed the Merlin likes to 'conk out' if you reduce throttle & therefore rpm too much. I had this happen couple times while taxing & coming into approach finals.

Lets build up a good picture how how to get the best out of the British fighters and feedback to the Dev team as what needs addressing before the patch goes to Steam.
