RE: PL Excellence
If it's the stock tube, it should be fine.
I've got two- one kit and one that's flying. The one that's flying is the 3D version and I've not seen any evidence of abnormal wear with it, and I'm the third owner, and the airplane is nine or so years old. PL normally has a shorter, larger diameter tube. Just make sure your tube passes through the sub rib and you'll be fine.
