Rudder axial play at top hinge 0,5mm.
Max tangential play at elevator tip ± 10mm

*Pilot positions vary considerably. When the in-flight C of G is near the aft limit it is best to weigh the glider with the pilot in, to determine the exact in-flight position.
The maximum dry weight limit was effectively removed by TN 301-24 which redefined the max dry weight as the max weight of the non lifting components (including pilot) + the weight of the wings.
