FIRST PARAGRAPHS OF BUILD ARTICLE:
IF THERE IS ONE thing that is missing from the average flying field, it is the sight of an attractive, cabin type of rubber model, valiantly churning skywards, with its stubby undercarriage legs pointing down at Mother Earth. Change it! Just see the interested faces when you prepare to launch Orlik - you may even get a volunteer retriever or two! Whether you are a beginner in need of experience in building and flying such craft, or a modeller of many years standing in search of a little pleasure once again, Orlik is the model for you!
Construction is very basic and can be completed by the raw beginner, provided he takes his time and exercises a reasonable amount of care. As this is not a contest model, wood selection is not critical, but it is advised to choose medium-to-soft wood throughout, and to 'match' such items as fuselage sides, spars etc to prevent distortion. Start with the wings, making the starboard panel first.
Cut the trailing edge to length and notch to accept the ribs before pinning down over the plan. Pin the lower 1/8 x 3/32 in spars to the plan, again cutting to length. Glue the lower 3/32 in ply dihedral braces to the spars. Cut out all the ribs, and mount them in position, followed by the leading edge and remaining dihedral braces. When quite dry, add the top spars and 3/32 in sheet gussets. When this has dried, lift the wing tip 5-1/2 in off the building board, to suit the dihedral angle, and build the port panel in the same fashion. Finally, add the 1/16 in sheeting between the ribs at the centre section (top surface only), followed by the soft block wing tips..."
