Hello! I have played FB a lot and I think the differencies between Hurricane 1940model and BF-109 Emil is not so huge. I mean that the BF-109 should climb a lot better than the hurri. But especially in online gaming it doesn´t mean that much. The battles are turn based battles but in BOB there could be a bigger difference between RAF turners and Luftwaffe climbers. Or maybe I´m wrong.

In FB/AEP Bf 109 E is better at low alt, at medium alt better is Hurricane II dot know why. Of course Hurricane II had engine Merlin XX with 2-stage supercharger so should be better than Hurricane I but i think still should be worse than BF 109 E.
Still in FB/AEP some planes have too good climb rate. Expecially planes with Allison engines like P-40, P-39 had too good climb at high alt but Spitfire MK VB 1941 too. It would be nice if Oleg Maddox will fix these in future patch and moddelled more detailed climb rate of high altittude of these planes.

The Merlin XX had good high altitude output for the day.

I've only seen calculations for Emil hgih altitude climb rates, but I've got fairly solid figures for the Hurricane II at 25 and 30,000 ft. At those alts, it's better than the Emil calculations I have seen.

What I'd really like to know about BoB is whether Oleg will model 100 octane fuel for the Spit and Hurricane, which will give the Spit a fairly large speed and climb advantage low down.

Climb times:
for BF 109 E-4: 6000m - 7:45


for Hurricane MK I 6096m - 9,8 min
MK IIB 6096m - 8,9 min
MK IIC 6096m - 9,1 min

I found some elese:

"The basic specifications of the Bf 109E follow (from The Fighter Aircraft Pocketbook by Roy Cross.

Wingspan:
32ft 6in
Length:
28ft 9in
Height:
8 ft. 1 in.
Wing area:
176.5 sq. ft
Engine:
DB 601A, 12 cyl. Vee, 1,100 h.p.
Max speed:
354.2 mph at 16,400 ft
Best climb:
2,990 ft/min at 13,150 ft
Climb to:
9,840 ft., 3 min.; 19,865 ft., 6.3 min.
Service ceiling:
30,100 ft
Combat range:
412 miles at 16,400 ft
Endurance:
1.1 hours
Empty weight:
4,431 lb..
Loaded weight:
5,600 lb..
Armament:
2-7.9mm fuselage guns, 2-20mm wing cannon (1/wing)."

So:
Best climb:
2,990 ft/min at 13,150 ft
Climb to:
9,840 ft. (3km)- 3 min.
19,865 ft. (6km)- 6.3 min.

There's a full test report on the Hurri IIb at Ring's site (though it's down at the moment, I think).

20,000ft (6096m) takes 8.5 minutes, at climbing power (1 hour rating)

Peak climb rate is 2710 ft/min

However, the question was about high altitude climb rate.

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>Best climb:

There's a fairly obvious flaw in that.

9840 ft in 3 mins is 3280 ft/min

9840 - 19865 ft is 10,025 ft.

10,025 ft in 3.3 mins is 3037 ft/min.

Yet best climb rate is given as 2,990 ft/min

At least one of the figures, either the time to climb or the rate of climb, has to be wrong.

I don't doubt the 109 had better climb rate at lower altitudes, but I still think the Hurricane would be superior at high alt.

Yes for me more accurate is 6 km in 7:45 for Emil but still better than Hurricane II 8.9 (8.5). Dont have info above 6 km climb rate (time). But dont think so Hurricane II was better maby was more close at high alt to BF E but not superior.

average climb rate from 0-6km
BF 109 E: 774 m/min
Hurri II: 685 m/min

why you compare the Emil with Hurricane MkII?
if you want a BoB comparison, use the Hurricane MkI, you sure won't see it very close to the Emil in most aspects http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Please! Let Oleg do his thing. If it's about BoB I'm sure he'll do his best to get it right.
