NX18235, with an A-65, is flying with the vertical fin offset to the left about 1 1/2". Feet off the rudder bar and the ball still settles about 1 ball width to the right.Offsetting the fin helped a lot and it is wise for builders to have a means of adjusting the fin.Greg Cardinal ----- Original Message -----

I offset my fin 1" and it is not enough (Continental A65, with a littleright thrust built into the engine mount). Mine also flies feet off withthe ball about a ball width to the right of center. I'm considering addinga small trim tab to the rudder - just a wedge attached to the trailing edge,not sticking beyond it.Jack PhillipsNX899JPSmith Mountain Lake, Virginia _____

Probably about 500=92 AGL. I rarely fly much higher than that. Takes toolong to get much higher.Jack PhillipsNX899JPSmith Mountain Lake, Virginia _____

As I recall (and I no longer have my jig. I think Steve Chase has it now),it has 9/16" right offset. I've got to make a run up to the lake thisweekend, moving my RV-10 project. If I have time, I'll pull the cowling onthe Pietenpol and measure it.Jack PhillipsNX899JPSmith Mountain Lake, Virginia _____
