Hi guys,

Some updates:

Two weeks ago I've got it airborne. But with a very strange behaviour! Flying around works fine, but if I tried to loop it rolls to the right!
But not only if I try to loop, everytime when i pull the elevator more than a few millimeter it rolls to the right!
Ok, first theory was that the music wire between the two halfs is too weak, so I installed a second servo on the left half of the elevator, mixed in the radio.
Better? No, worse! Now it snaps in a loop and it is almost impossible to fly. But, accidently I shut of the mixer in the radio (the music wire is still in the elevator), so the right half
of the elevator moved much more than the left and it flied almost perfect! Strange?!

Everybody on the field checked everything on this plane but with no result. Everything is straight and looks like it should!
I was flying with low rates on the elevator with about 40% of the recommended control throws, so this should not be an issue.

Any ideas?
