Been playing with bombers more often now and was wondering what the best climb speeds were or were to find them.
The aircraft guide has a bit of info, but climb out in a Ju-88 with a full load for example is slow and have tried diferent things but it just seems to lumber on up there

Thx

Hi Muddy17

Ju 88:

Take off: 2600 rpm (100%) 1.40 ata (100%)

Climb: 2400 (90%) 1.25 (85%. this setting is initial at sea Level. 85%. As you climb you'll need to open the throttle to maintain 1.25)

Best climb: 250 km/h IAS, 240 above 6000m
Trim into the climb.

Fast cruise: 2400 (90%) 1.25 (85% at Sea Level)

Cruise: 2250 (80%) 1.15 (59% at S.L.)
(there are guide marks on the relevant dials)

General Cowl flap (radiator) settings:
a) Fully open for all ground running.
b) Closed or part open for take off.
c) About half open for climbing.
d) More or less closed in level flight.

Take off boost should be maintained until the undercarriage is up and a safe minimum speed reached.

you are starting only with 100% throttle ??


the way i fly the Ju88 is very different.
i make the cooler open.

for start i use 100% propeller and 110% throttle.
i climb with 110% throttle till overheat message - than i reduce to 105%.

i close the cooler only in emergency to get the highest possible speed.

also i use seldom more than 50% fuel - more is seldom needed on the game maps.

I have also noticed how incredibly tough it is to climb with a full bombload on a Ju88. You really have to be careful on take-off as its a long haul. Also full throttle at all times apart from when overheating is very important.

It really does struggle into the air with 2x1000kg bombs. I think it was really a struggle for the aircraft to carry such a load IRL just as it is in the game, the Mosquitos (a comparable plane for enigne power and weight I believe?) top bomb load was limited to slightly smaller weights for its time in service (4000lbs vs 2000kg(=4400lbs)) possibly because it would have been a similar struggle for the Mossie to carry, as it is for the Ju88, but it was more critical that the Mossie kept its speed, having no rear gunner. Just a thought.

I also use full throttle with radiators open.

The Ju88 is a nice plane without such a heavy load put on it. Much closer to the Mosquito and Beaufighter than the He111 which is much more unwieldy and feels almost like a 'traditional bomber' in its manouvres.

I actually like the Me110 as a fighter bomber, I know the bomb load isnt quite as big, but its much more survivable than the Ju88 or He111. Much closer to the Mosquito, as in its quite manouverable for a 2-engined plane.

I enjoy finding out about how these planes were flown and seeing if the basic limits work in the game, which isn't perfect but it gives convincing results in many cases. I'm happy anyway...

With a full internal bomb load and 100% fuel:
Flat out full power will get you around 360 km/h IAS at 2000m.

2400 1.25 with cowl flaps half open will give 340 km/h IAS at 2000m. You do need full positive elevator trim in auto to maintain height, 'though.

2250 1.15 with cowl flaps closed gives 300 km/h IAS at 2000m.

With those SC2000 monsters slung underneath, It's not a problem to climb using 2400 1.25 at 250 km/h IAS on the Crimea map.
At full power with flaps, the take off is long but not really a problem unless the runway is short...

No need for full throttle all the time if you ask me, but, each to their own...

Good Info guys thats really what I was looken for in the JU88 thought I was doing somthing wrong. With your settings OMK 250IAS is easy to keep and a steady climb, I was using more power and only getting 220ish. I see an improvment already but it is still a long climb to 5000 lol.

Any other bombers anyone would like to share, I fly them all and find that HE-111 is the best climber so far.?.?

Just out of interest:
He111 - from various sources (will do for both types)

Take off: Full power, Flaps
Climb: 2500 rpm 1.32 ata
Best climb: 225 km/h IAS (IL2 Compare shows 212 km/h)
Cruise: 2400 rpm 1.30 ata
2400 rpm 1.25 ata
2250 ata 1.15 ata
Blower stage 2: 2,800m
Best speed at 2,000m and 6,000m
