Consult  the POH for the proper hang point for desired trim, speed,  and loading at this time. Attach the backup cable at this time  also.  [Figure 5-29] Insert bottom battens for a double surface. If inside a hangar  where there is no wind, this can be done by putting the nose  down, making it easier to install the lower battens.  [Figure 5-28] If not already accomplished, lift up on the back of the keel  and put the wing on its nose. Lower the undercarriage mast  and line up the undercarriage behind the wing exactly in the  5-11
