2.4.3 Wing Tip Construction
2.4.3.1 Material for outer Wing Tip
1 sheet 3 mm balsa ribs
1 sheet 2.5mm balsa ribs
1 sheet 1 mm balsa sheeting outer wing
1 sheet 1.5mm balsa trailing edge for wing
1 strip 4x10 mm balsa leading edge for wing
2 strips 4x2 mm spruce spar caps wing tip
1 angle template 6° (plywood) for alignment of the ribs (dihedral)
2.4.3.2 Construction of the Wing Tip
Construction of the wing tips is the same as the other wing parts.
Glue the bottom spruce spar to the trailing edge of the bottom sheeting. Bottom sheeting extends out
past the wingtip. These photos are not from the X-RES and differ in details.
Fit the spar shear webs and ribs. Angle rib C1 for dihedral using the 6 degree ply template. Washout
3-4 mm can be built into the wing tip, or it can be done with the covering later. Glue ribs, spar webs
and bottom spar together. There are no shear webs between the first two sets of ribs. A plywood angle
part is put in here later.
Remove from building board and glue on trailing edge from the bottom side.
Glue on the top spar.
Glue the ribs in front of the spar to the bottom sheeting. Glue the wingtip on the outer rib and bottom
sheeting. The wingtip is on the 4mm balsa sheet.
