Has anyone found a way to reduce the amount of dutch roll? I've searched the forum but haven't found a lot of info on correcting whatever's causing it.
My RV-7 was rigged per the plans and has flown hands off with the ball centered since first flight (about 60hrs) but, it has quite a bit of dutch roll tendency with and without turbulence.
I flew the first 20hrs. without wheel pants and fairings and was hoping adding them would help but that wasn't the case.
All control surfaces have been checked and adjusted to have almost a perfect shape using a straight edge back to the trailing edge radius. There's also no measurable twist in the wings or control surfaces so I'm stumped.
I've tried using a slight yaw, feet off the pedals and both feet hard on the pedals with nothing solving the issue and possibly making it worse using hard pressure on both pedals.
I'm flying solo with a W&B ARM of about 81.5" except for a couple flights with ballast at gross weight so I'm not sure if W&B has an effect.
