reported Huey skid aft part bounces then breaks off on surfaces

[winghunter]

This asset is used i.e. in the Padadise Lost campaign.

When landing on one side of the pad, it will bounce the helicopter upwards and destroy it. Eventually the landing pad will be destroyed as well. Test mission is attached.test sandbag UH1.miz

Hi. Judging by the textures, it seems that you landed too hard, which caused the sandbag to collapse. Once collapsed, the surface is not usable to land anymore.

I tried to land as soft as possible. Though in any case it should never bounce the helicopter 1 meter upwards and even damage / destroy the helicopter. This behaviour does not happen on other landing surfaces.

Attached is a track file

the skids need to touch the sandbags with the lightest of touch, and they will explode

OK, I think I see what is going on. Some sandbags are protruding. Maybe the damage model box does the same, which might hurt the skids. It's now reported.

Thanks.

Thanks.

Just to add to this. I believe it depends if you land on the sandbags with both skids. Vertical speed/angel  might have impact too.
Pardon my flying. Little rusty in the Huey. After I successfully landed twice, I slid the skids onto the sandbags on purpose, took off again, and then I landed with both skids on the bags on purpose. Kambom, twice.

Seems to be a huey problem after all. Just happened to me on these buildings as well, which even set the buildings on fire. (Thankfully i suck at landing in the center of objects)

I tried but cannot replicate the issue with roofs.

I watched your track file. You need to land with the last section of the skid on the edge. 

And you set the building on fire  That skid is a force of pure destruction

I frequently set buildings on fire with the Gazelle in Caucasus. It's probably due to the fact that "all" objects in DCS are there for your enjoyment of destroying them.
I guess a lot of objects has hitbox/damage model issues. And especially for helicopters, ground effect issues. Might be why it's hard for you to land in the centre.
In the Argo campaign for the Huey. It was impossible for me to complete the campaign, because you were supposed to land on a roof in the last mission. No problem doing that, except the building slid you off the side and caught fire. The campaign devs solved it by letting you land on the ground in the vicinity. I accepted the fix after a year of grief, while I don't understand the problem with the building was not fixed, as the mission must have worked when they made the mission. In the end, it's unfortunately one of the quirks with DCS.
Cheers!

The buildings are very fragile, like Hollywood props.

But still it shouldnt break the huey skids and throw the helicopter 3 foot into the air on the slightest touch.

I've compared the Gazelle and the Huey in the model viewer: a "bone" is protruding from the back of the Huey skids. I'm not sure whether this can be the source of the issue or not, but that is definitely the part you're talking about.

I'll test again.

Hmmm... That's interesting!

@winghunter You're 100% right: the issue comes from the Huey. I've just reproduced the issue on a "PAD single" FARP. I landed properly, then slided aft, until the tip of my skid overpassed the tip of the pad. Skid gone. I'll edit my report.

Many thanks!
