The senorita is nice plane , it has just elevator and rudder controls , I assume that the kit came with either fiber or wood dowels for control rods?

sounds like your pots are set to low ,try turning them up a little and see if the surfaces will move farther , also be sure and center the servos before connecting the rods , with the control surfaces centered you should get quite a lot of movement , from them , then you can adjust them to recommended deflection ,
