Skybolt rolling left at 155mph

[JeremyHolt]

Hey guys, I am new to the Biplane community as only owning one for about four months. One thing I am starting to notice is that my plane the faster I get, around 155, it wants to start to roll left. I have spades installed on the plane and someone told me to check these. I am going to remove them on the next flight and see if that makes any difference. Other than that I would think it would have to be the rigging. Where would I start with this type of situation...?
