lyotchik,
I am putting a 5985 coreless digital on the rudder. This servo provides upwards of 170 oz. of torque at 6 vt. the other flying surfaces are 5925s which are at over 120 oz of torque. These should be sufficient for this size plane and a 225mg for the throttle. If you have any questions about the plane or the build feel free to pm me.
I have been looking for a battery for this plane and am going to go with a 1100 ma A123 pack at under 4oz it should give at least 3 good flights before recharging which will take less than 15 minutes on a cellpro charger.
