1/16 music wire front rubber band wing hold down.  Due to the minimal support at the upper windshield corner these wires were installed to tie into the middle fuselage longeron.

                                The wire is CA'd to the longeron and servo mounting plate.

                             Battery box from 1/64 ply with 1/8 balsa  edge supports.

                            

                            Installed.  Note the 1/8 balsa corner support at the top front of the battery box.  One is also installed on the bottom front.  There is also a balsa cross member added underneath the aft end of the box.

                           Scrap balsa was added to the outside of the wing hold down tube gussets and saned to fair with the fuselage top longeron and upper side stringer.
