Hi While flying in the new desert map I was @ 80 throttle & 80 pp & it still overheats like mad even after reducing throttle to 70 % it wouldnt cool down Finaly I went to 50 % throttle /80pp Finaly it stoped overheating but the second I went back to 70 throttle its overheating like mad, It seems realy overdone, is it just me or is this correct ?

I second that, the Spit handles almost like it was fitted with variable-pitch prop.
I never read anywhere that the automated radiator in the Mk IX should be this faulty, and I really hope we're talking about a bug!

Same thing happens to a BF109/G10 even at 3000M Altitude. Beats me if its right or not http://ubbxforums.ubi.com/images/smiley/354.gif

The Spits and Hurries both overheat at anything above 80% power on even regular summer maps. Flying above 3000m remedies this. I have no idea if this is correct or not.

All planes suffer overheating on desert map.
BTW: just fly the spit above 5000 meters and experiment the UFO effecthttp://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

Lastnight I flew 109's in a desert map online. They heated up really quickly and took forever to cool down. I guess you gotta expect this in a desert. http://ubbxforums.ubi.com/images/smiley/16x16_smiley-wink.gif

Host missions in the evening or Morning and it works out alot better. I hosted one the other day with a Thunderstorm. LOL No overheats but what a PIA to fly.

From comments by a chap who's (recently) flown a real Hurrie, those merlins were really sensitive to poor management of engine temps. His comments lead me to suspect it's probably not far off accurate.

I have a copy of the cooling report on the Spit LF IX. In the report, they were testing 25 lbs boost, whilst the IL2 Spit IX is limited to 18 lbs, so should run cooler.

Level flight runs were carried out at 3,000 ft (just under 1000m) and 13,000ft (about 4000m)

At both altitudes, with radiators closed, the Spit came nowhere near overheating after 5 minutes at WEP.

The same is true of cruising speed, the plane was nowhere near overheating.

That applies to tropical and temperate summer conditions.

There was little difference between the results at 3,000ft and 13,000ft.

Q : "Is the Overheat Overmodled in the Spits?"

A : YES ..... they dont overheat at all unlike other planes up high

Interesting.
A point though is you can drive a car at 100kmh in 5th gear and it wont overheat, drive the same said car at 100kmh in 1st gear and it will overheat.

Will we have Vokes filters someday? Desert skins look weird without Hurris and Spits opening a big mouth under nose...

Sorry Tully but I disagree. There is something rotten in the state of Merlin in FB. Whilst I agree with you that poor engine management of engine temps is bad practice, proper engine management still leads to problems. Below is a page taken from the Pilot Notes for a Spitfire Mk IX (with time constraints).

http://www.lima1.co.uk/deerhunter/spit18.JPG

Try them out, it's quite difficult to obtain the combat settings and the maximum climb unless you're above 3,000 metres.
BTW the figures (with the exception of boost settings) are uniform across the Merlin engine range of fighters (haven't checked bombers) which leads me to believe that the figures come from Rolls Royce directly.

For pete sakes read the post....

I didnt use poor managment 80throttle 80pp?
Then the Instant it said Overheat I went to 70throttle & 70 pp
waited about 2 min still wont stop overheating then went down to 50throttle 60 pp Then finaly it stops OH... So I rais it too 70 throttle & it OH instantaly again Thats bullcrap how can you even call it a fighter ac if it wont run @ 70% throttle ?? I was @ 2800m btw.... & not engadged.

I think even for the desert this ac overheat is about WAY TO DAMED MUCH !!!

No I dont have any books or any documents but this seems like common sence I can even fly german ac @ 70% throttle in desert on the deck & Cool the engine
So why is the spit so much differant??????

IMHO The Automatic Radiator is Bugged in AEP & IS NOT WORKING like its supposed too....

Badsight I guess you never fly spit http://ubbxforums.ubi.com/images/smiley/52.gif

locust thats only on the desert map

and badsight is RIGHT
try it on any normal online map and the spit doesnt overheat at all at full power above 2000M

so yes its a bug

Assuming the sim models spits accurately those figures will apply only on one map (IIRC the Crimea map) which Oleg has set up as standard atmospheric pressure & temperature. On all other maps the time to overheat will be longer or shorter.

I'm not saying the game is right either, I'm simply saying that a recent article I read by a chap that flew a Hurrie stated that he had to be VERY careful with high throttle settings to avoid overheat, more so by a long way than any other warbird he'd flown (includes Zero, Bearcat, Texan, Constellation (mil version) and several others).

Absolutely Tully, obviously if you use high throttle settings you run the risk of damaging the engine. However, according to the ingame settings it's virtually impossible to reach 90? in the oil temperature gauge below 3000 metres which is the normal operating temperature of a Merlin engine. With combat settings you're obviously putting tremondous strain on the engine and hence the 5 minute limit but even using the climb settings is risky as the engine overheats well within the 60 minute limit.
However, all this is thrown out the window by climbing above 3000 metres where the Merlin doesn't overheat at all ingame which clearly is wrong as the data indicates.
The squadron I fly with uses the Hurricane Mk Ia since FB's original release (we used Yak 1s in IL-2) as we fly a Battle of France campaign. Originally the Hurricane was very difficult to overheat and you could use 100% throttle very liberally, this soon changed with patches so you had to be careful. But since the latest 2.1 patch, it's become worse and virtually impossible to use high throttle settings for any period of time unless I'm above 3,000 metres. I now find myself having to enter combat relying purely on being above 3,000 metres or sticking to a cruise setting.
Anyway I'm going to pass on the information I have about safe engine settings (Hurricane II, Spitfire II, V, IX and Mustang III) to Oleg and see what happens.
