HS 129 is really just fun

[Swing]

First of all, it is necessary to understand a very important thing about the engine management of this aircraft: When the management of the propeller pitch is set to Automatic, the revolutions / minutes are blocked on 2750 and the intake pressure limited to 1.25 ata . (combat mode).
The only way to obtain other settings is to switch to manual propeller pitch management.
Last thing, the admission pressure necessary for takeoff (1.5 ata) is obtained only through the boost.
To summarize: the automatic mode is only intended for ascent and combat, in any other circumstance, the pilot is supposed to manually adjust the propeller pitch.

 

For takeoff your checklist is as follow:

1. Set prop pitch to manual and adjust it to 40% (for 3030 rpm)

2. Set mixture to 'Reich' / rich (100% is for startup only)

3. Enable boost (ctrl+b by default) to unlock takeoff power (1.5 ata / 1 min)

4. Trim it halfway to full tailheavy depending on load

5. Rudder trim should be neutral

6. Set flaps to takeoff with a single press of the flaps button (they extend automaticly to takeoff position)

 

When you're ready to go quickly apply full throttle to increase the rudder efficiency. Its sometimes required to counteract any breakout tendencies with quick brake action and differential throttle.

Holding the brakes to let the engines rev up before rolling can also help to keep the aircraft straight on takeoff.

 

For climbing after Takeoff:

 

1. Enable auto Prop Pitch to maintain combat and climb power RPM (2750)

2. Disable boost

3. Full throttle (1.25 ata)

 

For Cruise:

 

1. Disable auto Prop Pitch and adjust it to 2350 (at this point it's a manually adjusted variable pitch prop)

2. Reduce power to 1.1 ata

3. Reduce Mixture to Normal

 

For Combat:

 

1. Enable auto Prop Pitch

2. Full throttle (1.25 ata)

3. Set Mixture to 'Reich' / Rich

 

Some info on the aircraft systems:

The constant speed propellor unit: It's intendet only for climb and combat whereas under all other circumstances the pilot is supposed to manually adjust the propellor pitch himself.
The mixture unit works the same as in the P40 meaning that the pilot does not adjust the mixture manually but selects the mixture mode (Lean - Normal - Rich - Extra Rich).

The procedure for single engined flight is

1. Feather the dead engine prop (enable manual prop pitch control before feathering the prop)

2. Trim the rudder max to the side of the running engine

3. Run the working engine at not less than combat power

 

The manual recommends keeping an airspeed of 190 km/h for single engined flight to maintain a shallow climb. From what I tested so far this also works ingame.

I didn't knew that!

Fun plane and distinctive plane, agreed!

 

I`ve been trying the tank busting with Jade`s practice missions but have to admit, I need to practice a lot more. Not very successful ?

I haven't flown the Hs-129 in the last month. Is the AI working by now? I had given up a campaign project for the Hs-129, because the AI was unable to keep formation, ignored the assigned speed settings and regularly hit the ground during attacks.

Is there a way to see this except using the HUD?

Funny, I always did it the other way round, takeoff with auto and climbing with manual, and I never used boost. But I just read it in the manual, what you posted, so thanks for clarification. I will try that today, see how it works.

Personally I do not agree with auto pitch. I climb better take off better and got far better cruise speed with everything on manual. 
I use auto if attacked

Thank you all for the good info.

In Expert mode I can’t get the mixture handle to react to the input (neither button nor axis). What do I wrong? Therefor the engine always quits after a few seconds.

Edit: I added info on some post here, but it looks it is not here any more

 

(Or better;

1st key prop- and rpm+

2nd key prop+ and rpm-

Now you have all planes feel the same with this, without exceptions)

I had this problem. What I did was assigning two buttons to mixture for all axis. Actually a two way button that shows two on the interphase. You will see the yellow handle on left side of the seat move

I prefer auto for takeoff, so I don't have to watch the RPMs. If the gauge was in front of me, I wouldn't bother about, but you always have to look to the sides to the engine nacelles for the RPM. And the Duck likes to make instant turns during takeoff run, which you have to break away immediately.

Well I do the un historical thing by leaving the canopy open during take off. You can hear the rpm with closed too when down to 2200 rpm

Based purely on this thread, I took her for another spin. She packs a mighty punch but I still can't keep her in the sky. ?

I have started a career as flight lead and everything seems to be going fine formation, flight wise and no one hitting the ground that I have seen. 

 

I just did a quick career mission as a wingman and left it on autopilot  Cruise climb was 210-225.  Cruise was 250-260 otw to the target.  Planes bomb and strafe well (20 mm) Return trip cruise was 280-290.

 

For a campaign I would recommend that whether as flight lead or wingman, that the player is the only who gets a 30mm as the ai never seems to destroy a tank and quickly runs out of ammo. With the 101, that means out of ammo after 1 pass.  The ai seems to do a lot better with bombs.  This why I am flight lead in my current career so I can control what the ai has loaded.

 

I look forward to a follow up of your Lion's campaign with the duck's.

The trim gauge was deleted for our version of the duck.  In previous versions there was a gauge right by the switches but I imagine this was in the way of getting in/out of the plane.

Make sure that you hit the all engines button before moving the mixture lever, it is the only way it will work.  When you spawn in, set the mixture before doing anything else, but if you have selected 1 eng or the other you will have to hit the all engines button again even if both engines had been selected separately.

Thank you @LuseKofte and @Plurp, I followed your advise and voila: It worked. ? I could take the Panzerjäger for a spin. Great. Definitely I will fly this A/C often.
