Take about 20% fuel and a full bomb load, 18 50kg bay1, 10 50kg bay2, 4 250kg external pylons.

For bombing operations under 1km take the type j bombs/low level (selected bay must be open and bombs armed before dive run).

BOMBS: You must select bay# or all, mode(series/salvo/single), string amount(1-24 or infinate), and distance between bombs(1/5/10 meters depending on target saturation for series) speed(set to 500/600kph for dive,you will need a last second adjustment for speed) and elevation of target above sea level minus your elevation above target, (about 170 meters for Hawkinge if you drop just above hangers) climb to desired height(3.5km and above to use superchargers but reduce throttle before engage, you have a WEP as well)

Full acuracy needs the use of the IAS TAS conversion chart but not needed on a dive run realy.



1) fuel cock 1 left tank

2) fuel cock 2 right tank

3) throttle idle

4) prop pitch full

5) water/oil rads closed

6) deselect eng 2

7) eng start (sometimes they misfire, if so eng start again)

8 ) deselect eng 1

9) select eng 2

10) eng start

11) select eng 1

12) warm to 40c water temp

13) elevator trim counter clockwise 1 revolution to 12 o'clock (take off position)

14) There are four indents for the flap lever. Set flaps one step up from bottom lever position (Landekl/landing position 50 degrees deflection) you will hear them activate, then move the lever one more step up to 0 position when the indicator under the airbrake for flaps reads .5 with the cursor or the second dot down(take off position 25 degrees deflection) The top and bottom positions stow and deploy flaps. There is an indicator to the left and below the flaps lever(near the gear indicator) the position should be between flaps down and up(second notch or .5 if you hover the cursor)

TAKE OFF: from a full length concrete runway like tramecourt in the ATAG server. Open water rads and oil rads 30% on taxi, open 100% on take off and climb. Spool engines up to 100% throttle/rpm and full pitch with toe breaks deployed, release breaks and focus on a nice straight run with no back or forward yoke pressure(tail will lift on its own) apply slight back pressure(rotate) to the yoke at 180/185 kph (any slower you will stall, faster and you will overspeed tires), gear up on positive rate, throttle back to the yellow mark on manifold ATA pressure indicater/rpm (30 mins in yellow at climb), level out and gain enough speed till you can stow the flaps(200kph or so).

CLIMB: Adjust throttle (mostly), prop pitch and trim through out the climb phase to keep manifold pressure and rpm at the yellow mark and the speed at 250kph for max climb rate (remove front gun for better visability in cockpit)

DIVE: Reduce throttle to 0% prop pitch to 30-50%(rpm under yellow during dive) and water rad/oil rad 0% and use elevator trim for a nice dive angle or you can use the dive break but it uses a bomb drop mechanism that deploys automaticaly(it sets trim auto for dive) and pulls you out of dive as well(it's the same system as Ju87 Stuka), angle is steeper but speed is reduced.


That's what it takes to get the 88 started and up in the air on a full real server.

If anyone has questions regarding Ju 88 operations(or any plane for that matter) feel free to join ATAG TS3 coms and we will help whenever possible.


Enjoy!

Great post Boris, I think I'm going to make the JU88 my next project.

I tried the 88 a couple times last week but couldn't get her off the ground without stalling. I think I know what I did wrong now thanks to your post; (too much fuel).

in Il2 series was among my preferred plane, I flown a lot of mission on line...really amazing. I'll practice hard to be competitive in CloD online sessions.
Cheers
