I am finishing my extra 260 and I noticed that there wasnīt a tight fit with the stabs....so I added some little double sided tape pieces on the side of the stabs, so it will fit tight, I had to push both stabs together a little hard so that the screw will go in to the hole, now I have a really nice fit, havenīt flown it yet but I was thinking some days ago to paste the stabs, I think I will do it eventually...
I had the same problem with my showtime, and the tube moved a little inside the fuse, I used epoxy and that was it, again I had to push the stabs together a little hard to be able to install the screw and today all the harriers I did were rock solid...
