RE: EF Extra 260 480 trim question
The wings on mine had to be balanced by adding weight to the left side.
Pick up the plane by holding the spinner and tail. If one of the wings dips every time (the same one, of course), then ad some weight to the other one. I used different size screws until I found one with the right weight to balance the wing. I simply screwed it on the edge of the wing and that solved the problem.
This solved my problem.
