Besides giving passenger Marc the mandatory RV-Grin (which i’m lead to believe will have a lasting effect ;-) we tried to trace the source of the aerodynamic vibrations in the cabin floor. It’s hard to compare it to other airplanes and is definitely not bad, but in the longterm, less vibrations is always better for the airframe.
For that purpose, we taped some small tufts to the cowling and mounted a gopro digital video camera to the right gear wheelpant.
One thing that is evident from the videos is that jumping castle the “Louvers” cooling aides in the bottom cowl work perfectly while the vibration most likely is generated by the current shape of the cowl outlet around the exhaust/nosegear mount. Already thinking about possible mods.
