Quest (oz1720)

About this Plan

Quest. Radio control sport model. Single channel, on either ailerons or rudder. For .5 to .8cc power.

Quote: "David Boddington's 35-1/2in span Single Channel Radio design.

Try to organise a building schedule before you start this project, and keep to the programme, don't start on all the interesting parts and leave the dull items until last. Cut out all your sheet parts before commencing building and build the wings and tailplane first. You should find construction straightforward with no particularly difficult parts. Choose the balsa wood carefully for lightness and eveness, especially the fuselage sides.

Wings are constructed in two sections and joined together with dihedral braces. After soaping the drawing, pin down a piece of 3/4 x 1/32 trailing edge. Cut 1/8 square hard lower spars to length and pin in postion. Cut wing ribs by the blocking method, afterwards cutting the root ribs due to the narrow spacing of this rib. Glue 3/32 and 1/16 wing ribs in position shown and check that all are vertical except for the root rib, which should be angled from the root rib template. Glue the top spar in position.

Fix the top trailing edge in position and glue the leading edge in position. When dry remove from the plan and sheet in the upper surface of the wing from the rear of the top spar to the leading edge and from root rib to the tip. Add 1/2 in soft balsa tips and sand paper, together with the leading edge to smooth contour. Construct the second panel in a similar manner.

When both panels are set cut slots in the first three ribs to receive the dihedral braces. Check these for accurate fit and then glue into position on one wing panel. When dry add the second wing panel to the projecting dihedral braces, glue thoroughly and pin down, prop up the opposite wing tip to 2-3/4 in to obtain the correct dihedral angle. Hold firmly in position until dry, pinning the two root ribs together. Sand and prepare for covering and glue trailing edge stock reinforcement.

Cut ailerons from hard 1/16 quarter-grain sheet and sand and prepare for painting. Ailerons should be sewn to the wings after all parts have been covered, doped, and fuel proofed..."
