FIRST PARAGRAPHS OF BUILD ARTICLE:
THIS MODEL is designed to follow-on from the elementary trainer stage, and gives an insight to those contemplating competitive work in the rubber driven category. The construction follows very closely the principles laid down and explained in the building of the Tutor elementary trainer but some refinements of design will be evident, these being incorporated to permit a competition type of performance. Building time should be less, however, as all unnecessary features are deleted in favour of lightness and simplicity.
Begin construction by cutting out the fuselage sides, riot forgetting to mark the positions of the uprights. Using a PVA type of glue to avoid warping, add the 1/16 x 1/8 in uprights - making sure that two 'handed' sides are being prepared, not two identical ones!
Glue the tail ends together clamping with a clothes peg, then cut out all the cross braces which are of identical length. Insert two or three cardboard rec-tangles between the sides and hold with rubber bands while the crossbraces are glued in, making sure that the latter are flush with the outer surface and well glued at the corner overlaps. Fit the crossbraces on the tapering portions and glue in the nose and motor anchorage reinforcements not forgetting the ply doublers.
When dry remove from board and cover top and bottom with 1/32 in. sheet cross grained. To complete the fuselage add the 1/32 in ply nose former, cut the access holes at the tail end, drill out the motor peg holes to 3/16 in dia and lightly glass paper all over ready for the tissue covering. The wing requires 33 ribs cut from medium 1/16 in sheet balsa by means of an accurate template. Make the template from thin plywood following the profile on the drawing. Select the strips which form the leading and trailing edges carefully as the wing has no spar..."
