HS 129 B-2 take off issues

[flyingjocksimmy23]

Does anyone find this plane extremely difficult to get airborne?

 

I just cant seem to get this one into the air, it says it is supposed to pull left but it pulls extreme right

and no amount of rudder seems to correct this.

 

I have no issues with any other aircraft!!

 

Thanks

I understand exactly what you are talking about!  The Hs-129 is a tricky airplane to fly.  By all the historical accounts that I've read about the real aircraft, most pilots found it very sluggish and under-powered because of the mission profile it was made for.  With all of the armor surrounding the pilot and critical aircraft parts, it was a flying pig.  One thing I've found is to increase the throttle slowly, don't just "peg-out" the throttle to the maximum right off ("balls to the wall").  As you do slowly apply throttle make slight adjustments with your rudder and wheel breaks.  Once you get the feel of how the aircraft is reacting going down the runway or airstrip (with any cross-winds if present), apply more and more power until the tail-wheel lifts off... then apply full-throttle for the remainder of the take-off sequence until becoming airborne.  It's a very unique airplane and one I really enjoy flying.  I remember making plastic models of the Hs-129 when I was a kid and that the design was wicked looking!

Hope this helps,

The 'pull left' comment is wrong - the engines counter-rotate, so it shouldn't turn one way more than another. It does seem to be vulnerable to cross-winds, which may be your problem. Contrary to what CraigNT55  says above, I find it best to hold it on brakes and then run the engines up to full throttle + boost before releasing. Either way in the early stages of the run the rudder is ineffective, so you may have to give a quick dab on the relevant brake if it starts to wander.

 

I normally use about 1/4 flaps for takeoff, though it probably doesn't make much difference.

thanks very much for the feed back guys 

Brilliant.. nice to see the people on here are are friendly and polite ?

When on runway:

- use full power immidiately (not gradually, you need prop wash on your rudder)

- steer left/right on runway using brakes at first, not rudder, rudder doesn't have enough authority at low speed

[Chief_Mouser]

What bies says plus use Boost on takeoff. That makes all the difference to stability due to the extra power.

Cheers.

Thanks for the comments, I had the same problem.

[Hartigan]

And remember set prop pitch control to manual mode and boost ON. It gives you max rpm. It´s more stable on ground. AUTO prop try to maintain 2750rpm and cause prop wash.

[Blitzen]

Nearly impossible ...I have to play settings in Custom, and check off rudder assist to taxi & take off..

Set takeoff trim. A nice, healthy dose of UP on the elevator trim. If you don't, you'll end up in the trees past the end of the runway.

 

Give her a notch of flaps.

 

Hold the brakes and run her up to full throttle. Pull the stick all the way back and hold it there.

 

Release the brakes, keep that stick hauled back until you've got some speed up, then ease it forward.

 

Stay on those pedals, use quick taps on the differential braking until you've gained some speed, then kick that rudder as needed to keep it going straight when your speed is up enough so that you have some rudder authority.

 

When you land, don't cut the throttle back to idle. Keep some throttle on so you can steer and avoid ground looping, until you're slow enough to avoid the danger. Use differential braking to slow to a straight stop.

 

Hit "Escape" and click "Restart Mission" as necessary until you've got it mastered.

I forgot takeoff trim.

[FurphyForum]

Never had a problem flying this bird, ok only the first time I bought the plane but from then on no probs, however both my Fw 190's are a different story ?.  I have now just got the hang of them.....I think.

 

Funny how each differs,  as to one type is a pain in the arse and others are a pleasure.

Just pull the stick back when gaining speed up to 100km/h to keep the tail wheel locked.

Glad to find this thread, I gave up crashing this ages back, will have a go again now, thanks to all

Wow thank you for the tip with the holding back ? i wan´t able to get her in the sky.  What i don´t understand is the automaic RPM it feels like the HS is every time pushed to her limit. The only way i get her in continous Mode is to set the propellers to manuell

[[_FLAPS_]Grim]

Hold breaks until full throttle is the whole trick

[Sublime]

Yea. What everyone else said.  Id basically throttle up, flaps down a notch, set the trim up a little.. When throttlingbup hold brakes then let go when you get to 100 and press boost.  If you still havemt gotten her in the air by this point reading the other comments -

After releasing the breaks gain some speed. When you get around 50 km/h (when you stsrt having even a tiny bit of control over the planes control surfaces) *carefully* nose it down a tiny bit to try and get your tail off the ground. This has helped me in lots of planes to gain speed for hard take offs. When you nose forward *CAREFUL* you want to hold the plane in that neutral/ on 2 wheels run up until its fast enough you start climbing. Ideally you wont be pulling back and lifting your gear- you ll just suddemly realizr your plane is airborne and it comes up smooth.

Couple other things. With certain planes etc and weights its really hard to get airborne without flaps.  Theyre fine to use; but make sure you rememver what flaps do. I.e. create lift and slow the plane down.  You basically want flaps in very soon after you rotate to gain extra airspeed - but be careful if youre just clearing trees or something as Ive had my plane "fall" several feet with flaps being taken in.  And dont be discouraged.  Keep trying at it - the HS is actually a lot of fun to fly once you geta hang of her but she never had much speed. In an ironic way its vaguely comforting because in a HS 95 % of a sortie for me is "xxx at 300 km/hr"

Why? Lol itd be foolish to go slower and the HS just cant do better otherwise mostly

[Sublime]

P.s. dont feel bad. Play TAW. Amonth ago i got a duck. Proudly as thebchat went nuts with compliments.

I couldnt get the bastid airborne. It was almost humiliating!!!

Per the aircraft manual the tail wheel on the Hs-129 does not lock.

The person I was quoting was speaking of the Fw190.

Ah, I see that now.

 

Oddly enough holding the stick back still helps with the Hs-129 even without a locking tail wheel. It transfers weight to the tail wheel and helps keep you tracking straight.

[Arsenal53]

May be i've missed something, but before starting i have to set the mixture to 100% or 80% before anything else, if i only select an engine  and launch the start sequence, the control mixture becomes ineffective !? Someone knows why?

[56RAF_Stickz]

There is only a single mixture control - so cannot set for one engine individually. Need to set it when both engines are enabled. As far as I remember though, it doesnt matter when you do it, provided both engines are enabled (and before you start them)

Long story short...once upon a time when playing with expert settings (complex engine management) you had to set the mixture, prop, and throttle to certain positions (minimum values) before pressing [E] to start. At some unremembered version (back in version 2.0 series) an undocumented change was made to have pressing [E] do everything. This aspect held true for all the airplanes except when the Hs-129 was introduced. Meaning pressing [E] resulted in a successful start except for the Hs-129 unless you had set the mixture to some undocumented value (IIRC I used 30% as suggested by Requiem) prior to pressing [E]. Sometime this past year the Hs-129 was added to the simple start procedure, aligning it with everything else. But fairly soon after that change we started testing the Me-262.

 

With the introduction of the Me-262, additional key presses were required for engine start, all other airplanes were changed to add additional minimum pre-start parameters. Which is where you find yourself having to set the mixture before pressing [E]. 

[Arsenal53]

it is a strange affair:

i have an old X-52 HOTAS so only one throttle. i have assigned keyboard keys to select/deselect engines 1, 2 and 3 (for the Ju-52) . before starting i set mixture to 100% then select engine 1(which automatically deselect engine 2) and launch the start sequence. Engine 1 started, i deselect engine 1 and  select engine 2 and press start . the two engine roaring  i reselect engine 1 to have both selected but i can't set down the mixture the key doesn't respond. all commands are effective, throttle, propeller but not mixture???

 

[Arsenal53]

at last!?

i have solved the problem assigning a key to select/deselect "all engines", when this key is used i can adjust the mixture after engines started ? don't understand why we cannot adjust when using individual engine selection keys?

[Arahantandreweatock]

I kept spinning the HS 129 on the ground and could not take off, I found that as I only normally fly single engine planes I had not set the throttle for a second engine, this caused the power on the left engine to go up when pushing forward, but not the right engine, thus causing the plane to keep spinning every time I tried to taxi it.

Bound the right engine throttle to my joystick throttle and all good, I could take off.

[jollyjack]

Once up and at around 200 km/h i found strafing easier with flaps around 50%. am i crazy?

But with 4.007c strafing ground targets i wasn't able to blowup one T34 at all, what ever cannons chosen.  Pity, it used to work before. Good news for the T34 anyway.

No. Flaps give (or should give) you nose down attitude, good for strafing. This is useful in the Mustang as well.

[jollyjack]

Just tried shooting other ground targets with the Hs129; there is definitely something wrong. I really hit bm13s right in the belly, but they stay alive. (Quick mission test).

I think the Duck is a harmless bird since 4.007c anyway. You can only feed them, their quacks are useless. I give up.

 

ADDED just tried the P51D strafing, flaps set 50%  etc, but it also couldn't kill one German tank it seems.

You are trying to kill tanks with the P-51's guns?

[=TBAS=Sshadow14]

duck still kills tanks as for the P-51 dont think it ever could strafe tanks except in maybe the red tales movie because in there they can also do the Cobra Move.
