Uncommanded Roll

[ApacheDoctor]

During straight and level flight, (trimmed appropriately), the aircraft will go into an uncommanded left or right roll (depending on direction of turn).

 

I have a Virpil set up, properly calibrated and stiff springs installed. No dead zones are necessary, only curve has been placed on the TM Pendulum pedals. All complete hands off the roll exacerbates and demonstrates negative static stability during the turn. (If its a FBW, the stability shouldn't matter, it should stay straight and level).
