Inside my 1:4,6 F-16.
High quality and beefy ply-formers with carbon, correct amount of glue. It looks good to me.
I don`t know how earlier F-16`s is made, mine is the latest I think, really don`t know if anything is changed..
Are there HC formers in those earlier? How about yours, Ali or others?

In my oppinion, there should never be HC in elevators, formers behind TE of the wing, rudder-stabs or anything that`s ment to be beaten.
Btw, I drove up and down the 2200 meter runway with my balanced (slightly nose down) FEJ elevator today at +150 kmh, purely in my hand as before.. :-P
Dead stable, passed..
