CH-47 The front starts bobbing up and down, could not stop it until slowed down

[Ramstein]

while flying some supply missing on a Syrian map missing, my Chinook the front end would bob up and down until slowing down while approaching my destination. it was like the front end was oscillating. I tried  to try to slow faster pulling up and reducing throttle but it was still bobbing. It finally stopped bobbing when I got very slow for the landing. I have the settings all on auto. I was not using BOB (no pun intended). Anyone else have a clue?? (this did not happen before this weeks patch). No sling load.

When I first flew the chopper anything above 160 seemed to cause this same reaction. I try and keep it at 150-155 or below and it seems to fly without oscillating, at least for me. This was empty of cargo also.

I had this happen to me once on the ground parked and it was my Rudder peds not being centered (easy fix) then in the air at 120K I am sure It was my fault using the Trim that caused this to happen. I was fat thumbing the trim button set thinking I was releasing the trim but turning it on then on then on lol I don't know why I was button happy that day. after I freaked out about it I turned off the trim and it stopped nose bobbing. It has never done it again with the Trim being used the right way. It is a Odd effect when it happens.

Sounds like retreating blade stall to me. At such high airspeed, instead of getting a roll moment in a typical single rotor helicopter or a possible blade disk merge in a coaxial layout like. the Black Shark, perhaps this is the expected result with a longitude tandem rotor layout, or the Early Access attempt at the expected result. @47_Driver might be able to tell us more.
