Mine were the same way, I just filled it in with super fil and blocked it out. Not perfectly flat but very close so it looks nice with paint. The weight is insignificant..with Super fil. My total airplane is only 1025 empty with an IO320 Constant Speed prop and nice avionics and light body filler on the elevators....

I had the same problem with the H Stab. I used foam covered with one bid of glass. I think this was lighter than filler. Super Fill is a very light filler as well for fine work. You will have more elevator authority after your fix.

Stan,

My Elevators are bowed concave in my 360. Upper side more, lower side less. (about 5mm)

Flying since 70 hours now but never felt a difference.

I did not want to spread much filler on the skin, as you add a lot of needless weight.

You also have to add a lot of counterbalance weights.... So save weight where you can!!

The leading edge of the elevaters should be flush with the horizontal skin, so the airflow stays laminar when it

goes over the gap.

Same with ailerons: keep the skins flush or thicker.

I think the Legacy horizontal are the same as the 360 MKII

Do I need to fill in the concave shape to create a straight Elevator surface or just prime and sand what I have?
