Hello Czirh,

The technical datas of this servo look good (enought torque, metal geared) even I don't know this mark (quality ? ).
Therefore I would choose a bigger one because your glider will have large and probably heavy ailerons causing relative strength (later movements) between servo and structure. With a bigger size the servo's case will be better maintened in my opinion.
In all cases the metal geared servos are necessary with small servos.
I remember a glider with which one I had plastic gear to replace after each landing Mad

Good luck

Hello

If you have more place in the wings, take biggest servos (C5077 for exemple, it's not very expensive , more torque than DS-929 mg and better resistant for choc)

Thanks , Texier and Erwan.
Bigger servo is better for the ailerons.
