This has come up on the ''Elan has arrived'' thread and the opinions have been divided, except that the incidence pins need to be glued into the stub wing, to prove this rig the whole ariframe and grab hold of you tail and move it up and down, it shocked me how much movement there was.
I would not use anything else, but metal geared digital servo's on a main control surface.
I don't use a UAT and all my batteries are in the back under the tank, using a P120SX, my Elan has never flicked out or run out of elevator, all set up as it came out of the box, roll rate is very impresive and so are flick rolls, humpty bumps can be performed very quickly in fact on one reversal according to my GPS I have pulled 9.6G without any flick out or problem, so the long and short of all this is check your incidence pins I think your booms are moving.
My two penny worth.

Agree here too... lived it..After my "hard landing", the booms were much sloppier. Had to tighten them. Also make sure your stab is stiff. I had stress cracks in the stab after 50 flights and one hard landing. It twisted easily. Ben burden noticed it in how sloppy the pitch control was and we landed it and found it when pulled apart. Thats something to watch more over time than new.. But the pins might be a little loose.
