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.

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.

I took the Spit 100 to a ride.

- it seemed to me that it still not hitting 100 octane performance, still 280 mphish, even with boost and +12
- breaking the aircraft in dive is not possible with elevator only, only if trim is used to assist
-roll rate at high speed seems to have been reduced (which is correct no measurements yet)

[trademe900]

it's unbelievable, they are actually very slightly slower now would you believe!

100 octane at sea level:

hurri 255/275mph

spit 260/280mph

still hand grenades too.

I'm finding it difficult to adequately phrase a response to all of the threads relating to this latest patch without incurring a further infraction of forum rules.

When the Blenheim was deemed 'unflyable', I listened, studied, flew to destruction, then made tutorial videos. I hope I got people flying, and restored some faith.

When people were having problems navigating and understanding the course setter and gyro in the RAF planes, I listened, studied, flew in the wrong direction, flew in the right direction, then made tutorial videos. I hope I got people steering straight, and restored some faith.

When the 100oct Spit was deemed 'unflyable', I listened, studied, flew to destruction, and made more tutorial videos. I hope I got people flying, and restored some faith.

Now I have little faith left myself.

I dont belive that they are not able to make accurate performacne and FM of these planes.

It was even possiblie to do in old IL2 - i mean maxiumum speed, climb rate, roll rate and turn rate with not such problem. I know beacuse i for some time i was making FM tunings and mods for IL2.

I just dont belive they cant do it for CLoD.

Give me paramaters and FM code and i would do it for 2-3 weeks.

+ 1000
I'm getting the same results as MadTommy and trademe900 - absolutely ridiculous that this has not been sorted. My thanks to Kwiatek and ATAG_Dutch for their hard work, but I too have lost faith in whatever process have led to this cock-up.
