This is for any one that has a problem with their PA Extra 260. This is a very good plane, but there are issues with some of them, and now's a good time to solve them.

One problem is wing rock. Besides the obvious, 1st check for warps I had one in each ail. The rep from PA told me less expo helps too (more responsive) depending on your stick length and your personal preference. Also just being a small plane with little 3D experience. Any other suggestions would help very much

.

There is another problem with my 260 it flies tail heavy no matter what the cg 90mm 100mm doesn't matter. I'm not saying it is tail heavy, but just flies that way in regular flight. I am trying to get this resolved with PA. I might need a new fuselage I don't know yet. I have about 2mm down trim for level flight at 1/2 throttle. full throttle it climes like a banshee from level flight w/o any input. Landing requires even more down trim just to get the plane to settle in. If i don't give it down trim I have to fly it down risking the plane on landing. If there is any wind at all forget about flyng, I mean landing, it's a handful to say the least, but has to be done

(I live in the desert that's always windy). I'm pretty good at landing anything else, but this one. I think it's my plane in particular, and maybe others also. The plane has bad coupling to the bottom in KE. It could be the down trim. All tests indicate a tail heavy plane even though I went to the extreme and balanced it at 90mm on my machine, still flies tail heavy even though it's not. I don't have a lot of experience tuning an airframe, but this is defiantly learning me somthin' good. I'm hoping PA will help me resolve this problem they've been very helpful so far.
