the new English manual covers this. (thank you belsimtek!!)
it is dynamic roll-over caused by to much right rudder to early.
the lateral thrust from the tail rotor pushes you over. it wants to turn you to the right but as the wheels form a triangle. it tips you left and forward and unbalances the triangle and you roll over. especially if you have the wheel brakes on.
the square profile of the skids must prevent this being an issue in the huey.
and its lower profile.
so use less rudder until the collective takes effect. if this happens to you.
only use right pedal to counter left yaw. don't put it in early.
in the huey i was setting the rudder before raising the collective.
and that kills you in the MI -8
and i thought it was a cyclic issue...
but no,reading the glorious new manual and testing it, it is all rudder..
(I have just swapped racing wheel pedals for MFG crosswinds.. why my pedal and collective inputs are now more in tune.. no more needing to get the pedal right before raising the collective.)
so its a quirk of the mi-8 , its height, its triangle wheel profile, and the strong positive tail rotor trim built in for ease of cruise. (why you need lots of left pedal to taxi straight)
meaning right rudder on the ground can cause dynamic roll over.
its also a bad habit you may have brought over from the huey... rudder in to early.. like me.
