May be it’s a result of improved vertical stab efficiency? You installed fences asymmetrically - only on the top part of the vertical stab. So this part generates a weak turning force. Correct me if I’m wrong.
Happy landings!

Hi Sergey,
It could be as you say, but i should have noticed the roll coupling earlier.
As you can see on page 3, i first tested the fin fences, without adding anything to the fuselage. I don't remember them having any influence on roll coupling.
The short version of the fuselage fences (presented on page 3 as well) also didn't add any significant roll coupling. I only noticed this when adding the longer fuselage fences.
