Bugged collision model, airframe sinks into the ground

[Juancio]

When intentionally crashing the Huey after take off, but not hard enough to make it explode, the model sinks into the terrain mesh and then bounces back to sea level.

 

I noticed this problem when I first bought the Huey back in 2015 but didn't make a report hoping it was going to be fixed. Well I guess it was never fixed, hence this bug report.

 

To reproduce just roll the chopper immediately after it leaves the ground.

 

Thank you
