Steps To Reproduce
  1. Set flight model to SFM
  2. Take CH-67 and try to land on water while keeping collective very slightly bellow hover position.
  3. Observe the helicopter hover touching the water
  4. Attempt the same manoeuvre as with SFM
  5. Observe the helicopter pulled underwater at 0-0.5 m above surface
  6. Try to hover with a bottom of the helicopter touching water surface.
  7. Observe increased throttle requirement as compared to hovering few meters above the surface
Additional Information

The issue is much more easily and reliably reproduced using CH-53 from RHS:USAF as it floats well when SFM is used.

Advanced flight model just didn't have any water simulation, it's as if the water was air, and it just dropped right down through it.
Its looks a bit glitchy/bouncy and doesn't feel very good, but it's the best I could do.
