How is this possible?

[roborhead]

OK, somebody must explain me this video: http://www.youtube.com/watch?v=6M45Emu4qAw

 

How does the Huey fit under there!? Not saying this dude is cheating. Tho I cant even takeoff like that! Besides he is taking damage to the tail rotor. At least he says so. Thats why he must have damage on! He also does some crazy flighting in another video: http://www.youtube.com/watch?v=3amMB0rSz5M This makes me think his flights is not pure luck.

 

The questions is how? How can this be done? How can I learn this? I cant even move the view around that quick and smooth! What kind of setup do I need to do that?

 

I have already 100hours logged on the Huey but Im nowere near doing any of kind of that flighting. How many hours do I need to fligh like in the videos above?

 

Have a great flight!

Rob

 

EDIT:

On the 1st vid. why is he switching off(?) the trim thingy? OR does he switch it on? also why? Anyone know? Thanks!

He kinda cheats, he allows himself to slide on the ground. IRL big sparks would probably come off his skids. He is able to quickly move his view probably because he uses trackiR.

Heh, nice...

 

He probably did not care if the skids touched the ground and that the therefore was sliding/skidding beneath the structure. But impressive nevertheless.

 

How you can archieve the same? There is a three step approach to learn maneuvers like that:

1. Practice

2. Practice

3. Practice

;o)

 

Didn't notice what or if he switched something off - but it could well be that he disabled the force trim so that no forces were applied to the stick ... which would probably make only really sense if he is using a FFB stick where that would actually matter.

[Nage]

Well, its possible, i did a track made on virtual acrobatic server at Min. vody base made some stunts and going under bridges and skid only hit bump in middle and passing last bridge.

I never tried to go under airports gates but if it fits it can be done.

Vid is roughly cut and unedited mostly cuz i didn`t had space on HDD nor time, sorry.

Ah! Thanks! I didnt notice the sliding/skidding. I assumed because the radar altimeter shows 1 (Ft) he was actually flighing under the gates. but now I can clearly see at the start he seems to touch on the right side then later on the left side.

 

I can now (After watching the video a couple times) see that he actually bumps the last gate with the rear. You can clearly see he pitch forwards but then gets knocked back.

 

I also tried doing it myself again and the problem really is the huey fits perfectly but you can not pitch or roll it because then the rotor will hit the gate. But if you actually complete skid you loose too much speed and also turn left or right and hit the building or post. You must do a perfect level flight beneath it.

I didnt manage to do it so far :joystick:

I do. But maybe I should start with passing under power lines first. Then bridges. And then one day those gates!

That is probably it!

 

Another thing I noticed. The emergency landing. How can I practice those? Can DSC simulate arbitrary failures. Like in Prepar3d I know you can say when a specific part should fail. Because in the other videos of that guy he is doing autorotation landings (tho they are pretty sloppy and there are way better autorot landings on Youtube). He somehow manages to cause the engines to suddenly stop.

 

Also loosing the tail rotor to train emergency landing. I dont even know how that feels to fligh without a tail rotor. Dont want to think landing :cry: without. But somehow that guy pulled it off like it was business as usual! How can I practice those emergencies with DCS?

Thats amazing! How did you do the loop at the end? Every time I try something like that I loose my main rotor!

Also doing a takeoff like in the 1st vid I posted. I always loose my rotor!

 

I once saw a video on Youtube from the military about mast bumping in the Huey. But I dont think this is mast bumping. Or is it?

Either that or you're pulling too hard and the blades are hitting your fuselage. Obviously we can't see what you're doing wrong unless you post a track.

 

Flying the Huey requires all your control inputs to be smooth, gentle and measured. Being violent with either collective or cyclic tends to end up with bad things happening.

In the mission editor, you can select from any number of components you would like to fail.

 

You can choose a probability of failure, and a timeframe.

Turning force trim off doesn't do anything, unless you actually use trim. I've heard from a pilot that flew Hueys in the army that they never turned it on in the real thing (And you were considered less of a man if you did). All force trim does is keep the stick somewhere when you push a button.

You need to be pulling a LOT of collective to keep the G-load on the mast positive, if you don't you know all too well what will happen.

, flying straight and level gets boring after mastering it though. You'll start pushing the aircraft to its absolute limits, consequences be damned. It IS just a game after all. :joystick:

That what was exactly what I meant: without active force trim system, there are no forces applied to the cyclic and thus it can be deflected without having to overcome the forces all the time. In DCS this is also simulated if you use a FFB stick - it becomes "limp" as no forces are applied.

 

In RL as in DCS this probably makes flying more "twitchy" or nimble - which might be a good thing if you do crazy stuff like in the video.

What I was saying is that it only has an effect if you push the trim button.:smilewink:

Uhm, no ...? Don't know if we misunderstand eachother or the trim system ... :o)

 

1) Force trim active + trim button not depressed -> stick is kept in place, force has to be applied to deflect it

2) Force trim active + trim button depressed -> stick is "limp" and can be deflected without much force

3) Force trim inactive + trim button not depressed -> same as #2

4) Force trim inactive + trim button depressed -> also same as #2

 

That my understanding of how it is in the real helo, and how it is also replicated with a FFB stick (at least true for the G940).

As a side note, this is only true with the hydraulic control booster active, which is what prevents forces on the rotor system from affecting the flight controls.

The Force Trim system only serves to provide artificial centering forces.

THAT is very illuminating.

Do you know how many times he tried it before he had a complete video of these aerobatics? Maybe this is his 20th attempt? External view would be interesting to see. Unfortunately DCS doesn't take recirculation or other aerodynamical effects caused by buildings and other aircraft into account. At least the last time I tried to reproduce them, there was no effect.

He obviously has a good eye for the distance. But for the rest of his piloting technique I keep my comment to myself, because this is a "game", as b00ce says.

He uses trackir or something similar.

How many hours do you need? That is completely individual and can't be said in general.

If the fuselage of the helicopter isn't leveled, the radalt doesn't show correct values.

You could simply reduce the throttle to idle to practice ARs.

Before practising loss of tailrotor, start with fixed tailrotor pitch, as the helicopter behaves less violently then. Just push one pedal a bit and keep it in this position till you're on the ground standing still. Then try the other pedal.

 

 

Turning force trim off doesn't do anything, unless you actually use trim. I've heard from a pilot that flew Hueys in the army that they never turned it on in the real thing (And you were considered less of a man if you did).

, flying straight and level gets boring after mastering it though. You'll start pushing the aircraft to its absolute limits, consequences be damned. It IS just a game after all. :joystick:

 

If the force trim system is active, the force trim release button on the cyclic stick releases the force, so the pilot can reposition the stick and then activate the system again by releasing the button.

Your pilots obviously never flew a 3:30h IFR trip. Otherwise they would think differently of the force trim.

Without force trim I can fly more precisely, but that is more a thing of habits. On the other hand, with a FFB joystick in DCS and force trim on, it can help to reduce the helicopters movement during hover, as you only need small inputs and if trimmed correctly the limp area of the FFB joystick is sufficient for these small corrections.

 

Uhm, no ...? Don't know if we misunderstand eachother or the trim system ... :o)

 

1) Force trim active + trim button not depressed -> stick is kept in place, force has to be applied to deflect it

2) Force trim active + trim button depressed -> stick is "limp" and can be deflected without much force

4) Force trim inactive + trim button depressed -> also same as #2

 

That my understanding of how it is in the real helo, and how it is also replicated with a FFB stick (at least true for the G940).

That is correct and applies to the pedals as well.

 

As a side note, this is only true with the hydraulic control booster active, which is what prevents forces on the rotor system from affecting the flight controls.

The Force Trim system only serves to provide artificial centering forces.

As long as there is pressure within the hydraulic actuators, even with deactivated system, no forces from the rotor are transferred to the cyclic. But as soon as this pressure is lost, the rotor tells the cyclic stick where it has to move, and the pilot can do nothing to prevent this.

There is no centering in the Huey. The force trim system just holds the cyclic stick and pedals in their last position after releasing the button on the cyclic stick.

 

 

 

Basicly the Huey's force trim is nothing else than a spring that is kept in its position by electromagnets. Electromagnets off-> free movement without opposing forces. Electromagnets on-> you push against these springs. This is for all axis except the collective. There you have only the possibility to adjust the friction, so the collective sick movement is between totally loose or hard to move at all. Most joystick-throttles have the same function.

Wow! Thanks I didnt know this.

Yeah. Tho my 30th attempt doesnt look even remotely like that! :cry:

I also like to see different perspectives. I also like to see that guy hover.

His flighting looks dodgy at various spots. Tho he gets the Huey thru all those tight spots. Like you said a good eye for the distance.

 

He uses trackir or something similar.

 

Maybe I should get that too?

Thanks I will try that!
