I am trying to get my IMPACT dialled-in to my liking but I cannot seem to get it to roll as well as I like.

The rolls just don't seem to be as axial as I expected so I am taking a closer look at my linkage setup. I have tried different amounts of differential (yes, I have negative - more down than up) but it hasn't helped.


This is my first top hinged model with servos mounted on their side. I am not satisfied with my geometry with this configuration because of the length of arms involved. Can anyone give me some advice on the best approach to setup the geometry correctly. The angles look all wrong which I think is part of the problem. Ailerons are probably moving at different rates to each other throughout the entire travel range.


Thanks
