Slicker 50 (oz5501)

About this Plan

KK Slicker 50. Free flight power model. This is the Slicker 50 as published in Model Aviation magazine, 1948.

This is an enlarged version of the original 1947 Keil Kraft Slicker (oz8877) design.

Quote: "By Bill Dean. Winner of the 1947 All Herts Rally and 2nd place at the 1948 British Nationals. Build this 50in version of the famous Slicker.

Developed from the 42 in Slicker, the '50' version was a familiar sight at most of the 1947 contests. The original models were powered with the Arden .199 and the Bantam .19. Ron Moulton even equipped one with a Forster 29, but for general use nothing larger than an Ohlsson 23 is recommended. The new ED Competition Special is an ideal diesel for this design.

Slicker 50's were placed third and fourth at both the British and Irish Nationals - the fourth place in Ireland being gained on one flight only. Eddie Keil won the 1947 All Herts Rally with a total of 6:25 on two 15 second motor runs and placed 2nd at the 1948 British Nationals.

One-third scale plans are given overleaf, in which all the important parts such as ribs and formers are drawn full size. These parts will help you to draw up full size plans. For instance, rule out a 50 in by 7-3/4 in rectangle and draw vertical lines for the wing ribs. Now cut out the TE pieces and the ribs and place them in position to obtain the outline shape and spar positions. Adopt a similar procedure for the fuselage and tailplane drawings.

Building this model is easy if you follow these notes and the plans carefully. Before starting, note that the bearer cut outs on Formers F1, F2 and F3 are positioned to suit either the Bantam or the 2 cc ED diesel. If any other power plant is used, the bearer positions will have to be altered.

Fuselage. The fuselage is built up on the crutch system to ensure an accurate assembly. Taper the fronts of the bearers to allow for the 1-1/2 degrees downthrust - then mark on the engine and former positions in pencil. Glue a rectangle of ply to the Fl Former, place the undercarriage in position and attach it by gluing and screwing another piece of ply over the top. Thread F1 on the bearers and glue in place, followed by F2 and F3. Put aside to dry and build the 1/4 in. sq. crutch flat on the fuselage top view.

Remove the two front crutch spacers and attach the crutch to the notches in F1-F3. Cement F9 in place, join F10 to Fl 1 (flat on the plan) and cement in the notches of F3 and F9. Now drill the engine bolt holes..."
