About this Plan

Skywayman. Free flight sport power model by R.A. Parker, from Model Aircraft, October 1951.

Quote: "The Skywayman is a tough little airplane intended expressly for sport flying. It will take all the knocks you can give it and then some. The Kalper .32 diesel supplies all the power necessary for a zippy climb, in fact, we found that a fair degree of downthrust was needed to check that upward spiral, which for once, was just what we did not want.

Fuselage: Cut out all formers, and where balsa and ply laminations are required use Durofix, and dry under pressure. Bend undercarriage parts from 8swg, these being bound to the formers with thread, followed by a liberal coat of Durofix. Cut two fuselage sides from 1/16 sheet, sanding to 1/20 in thick, add 1/8 x 1/16 longerons and uprights not forgetting to make one left hand and one right hand side. Assemble fuselage, checking accuracy with set-square. Taper engine bearers to ensure correct downthrust, cement in bearers and check line up. Add 1/32 sheet cabin floor, then lightly cement in position the soft block which will complete the lower fuselage contour. This block should be carefully carved and sanded until the curves flow nicely, then prise it off lightly and hollow to about 1/8 in wall thickness, cement it back on again, this time for good. Add top and bottom fuselage sheeting, pre-sanding all wood. Block in around the nose, carving and sanding to the shape shown on the plan. Keep the edges of the detachable cowl as dean and sharp as possible.

Wing: Make two identical rib templates from 1/16 ply and sandwich rough rectangles of 1/16 balsa between them. Curve the resulting block to conform to the templates. Cut slots for spars. Next shape leading edge, mainspar and trailing edge - these should be slotted where required, dihedral angles correctly cut, and dihedral keepers cemented in position. Assemble the wing, one panel at a time, flat on the plan. Watch for unwanted warps and allow each panel to dry thoroughly before removing from board. Add leading edge sheeting, sanding the wood first, of course. Sheet latter half of centre section and cover the front portion with dear acetate sheet as shown on plan..."
