reported L118 Light Artillery

[Marsvinet]

Now that the L118 can finally be picked up without slamming into the helicopter, the next problem shows itself. When carrying at speeds below 40kts, it merely bounces around and starts swinging without any manouvering. Above 40kts, it gains enough energy to risk slamming into the carrying helicopter. Above 60kts, even a gentle manouver is almost guaranteed to cause the gun to swing into the fuselage. 

The gun is tested to be stable at 120kts when in a single point sling, according to US TM 4-48.10 "Multiservice Helicopter Sling Load: Single-Point Load Rigging Procedures". 

Attached is a track showing how it behaves in steady (except the gun swinging wildly enough to make it not steady) forward flight at increasing speeds.

 I was testing the chinook with L118 light gun and i tested almost all ropes and it is not stable at all. Any idea where the problem is? It is at cargo or at CH47F? The problem was on Germany map but while i tested it on Caucasus i noticed the same problem there. So i guess it is not the map.

What i noticed. If i take of trimmed and i do not used at all the Button of TRIMM REL it is ok i can fly it. But while i fly if i try to press TRIMM REL to use my pedals to bring the white ball centered the cargo starts to sling immediately.All this with the 100ft rope.

It feels  that helicopter has a YAW sensitivity

There was an issue that I believe was reported a few months ago, where attempting to sling load the L118 would result in it bouncing around, to the point that it would destroy your own helicopter.

I've no idea whether that was resolved.

It was addressed around July, we will take a look at these tracks soon.

thanks

Got a bug report for the same issue here: 

It's not Chinook specific, happens in Mi-8 as well. The picking up-bug from before is solved, now it is about how stable it is in flight. It should be stable in flight up to 120kts.

Threads merged. 

As I suspected there was a fix already but it seems it needs some more tweaking when in flight. 

We have reported it, thank you for the tracks
