My guess is this the cause. I'm not sure how to minimize this other than reducing the angle of attack an...

Hi Everyone, Thanks for the input. One of the guys in the club "Glen" went out and tightening the wires to see if that made a difference in flight. Here is a video of the stabilizer dancing around. https://youtu.be/Z1WhuC3XpLQ Needless to say, he made one go around the patch and put her ba...

However, we have run into things over the years. My club members are curious if other Pietenpol fliers notice the v...
