4 stupid questions concerning the JU-87


Recommended Posts

Posted (edited)

Did she have aileron trim?

 

How do I open the downward view?

 

Does she have mixture control?

 

Do you have to switch on the supercharger manually above 3km?

 

Since nobody has flown a real life Stuka...do you like the way she's modeled? FM etc.

1 Not sure

 

2 The bomb bay door key

 

3 Think it was fixed to/with the throttle?

 

4 Automatic? again don't know for sure.

 

5 I think its ok but I've never flown one.

I've had very little time in the JU-87 in this game. Enough to get a few skins unlocked but that's it. I need to fly it more after I finish all the reds.

Thanks, Blackwolf !

1. The stuka only have Elevator and Rudder trim.

 

2. Bomb bay door key, I guess the default button is "N".

 

3. Its been a while I played BoS, and I'm currently not able to play it, but I guess it was automated, like the 109/190 (someone correct if I'm wrong).

 

4. No, the supercharger has 2 positions, one for low alt, and another is the "automatic" position. I usually set it to the automatic and leave it there, never had a problem.

 

5. Well, nobody will know for sure. But imho, its pretty good, turns well (if you have the energy to spare), can deliver very accurate bombs while diving and it shows its drawback: it is a very slow machine.

Ju87 in BoS feels pretty good except for wobbling when throttle up.

1. In reality it had adjustable aileroun trim tabs. Not working ingame.

2. As others said

3. Automatic mixture contorll - npthing to adjust here.

4. Also automatic. You can switch the supercharger manually to Ground Mode for TO (not nessecsry)

5. The overall FM is ok, but it has some serious issues. One of them is it's TO behaviour when it's engine starts to rev forth and back at TO power making that squreechy noise. Also I think it's too wobbly at cruise speed (heavily tends to oscilate on yaw axis) and a little to vicious on stalls and spins, but I haven't flown a real one yet so it's just an impression.

 

Overall it's probably the best modeled Stuka yet in any sim with the exception of some weird bugs that I hope are going to be fixed this year.

Regarding FM, I also find the Ju 87 to be a little too arupt in its stalls, but I don't experience that directional instability, that some others seem to get. To me it seems extremely stable in flight and I can reliably place single shots from the BK with pin-point precision, something I'm not alble to do in the (also fairly stable) IL-2.

Really ? I had tremendous trouble until I learned how to do those precise shots with the BK cannons, I wasted so many ammo until I started reliable hitting those tanks. Maybe its just my lack of skill with the stuka hahaha  :rolleyes:

If you are in a LaGG-3 and the Stuka are a ACE AI, you will not like their "model".  :lol:

I just tried to fly a mission with the Stuka for the first time and i can't get that darn thing up to speed nor altitude. I always end up with a damaged engine after 3 minutes into the flight. But throttling back to 55% for continues flight isn't enough power to get even close to cloud level with a bomb hanging on your butt. Do i have to lower the prop rpm?

Yes. You have to keep prop rpm at 2100 and throttle at about 1 ata for continous flight. At this stetting you won't damage the engine and have cruise speed about 300 km/h.

You'll have to close your radiators if you intend to fly for more than 30 min with this setting.. Temp will be low if you don't.

Yep. Generally speaking 2100, 2200 rpm should be good for cruise flight, 2300 for climbing and 2400 for emergencies. Keep an eye for the manifold pressure too, usually 1.1 - 1.2 ata for general flight, 1.2-1.3 ata for climbing. And off course, manage your radiators as needed, do not let temperatures get past 100 ºC, or get below 40ºC

Power settings for the Ju 87:

 

Max continues:                                 1.15 ata | 2250 RPM

Climb (30 min):                                 1.32 ata | 2400 RPM

TO and Emergency Power (1min!): 1.42 ata | 2600 RPM

 

You can easily TO with TO and Emergency Power ingame up to ~50 m. You should switch back to climb or continues power as soon as possible to prevent the engine from taking long term damage. Usually, with heavy ordinance, I take off at 1.42 ata and throttle back to 1.3 ata / 2400 as soon as possible climbing straight.

 

Another thing to remember is to slowly retract your flaps once airbrone. You need to build up some speed first and trim it slightly tailheavy before rectracting them - otherwise you'll have an instant nose drop.

 

For climb power both radiators must be fully open (oil, cooling water). At cruise setting you can use the "Normal" setting on your radiator flap indicator to keep your temperature constant.

 

Don't go above 100°. Optimal temperature is ~ 80-90° for oil and water. Don't take off with  < 30° water/oil temperature. If you follow those requirements your engine shouldn't mess up. :salute:
