Tri Gear Yaw Stability

[daleandee]

My theory is the gap was killing the air flow on the right side of the rudder and letting the tail wag that direction. I can't prove anything but the tail looks better and it stays in line better. I also closed the gaps on the elevators and saw a change in the trim setting, telling me that the same thing was happening there.

Can't say how any of that would effect the Onex but I remember a number of years ago John Davis (founder of ASA) did the same thing on his Jabiru 3300 tail wheel Sonex. I asked if he noticed any performance change or handling differences. He told me that there was none he could tell. I believe he used clear Lexan in his experiments.

FWIW, I've never had anyone ask about the offset rudder but I myself was curious about it the first time I seen it ...
