Super Star (oz14004)

About this Plan

Super Star. Radio control pattern plane.

Quote: "Looking for the classic European style aerobatic radio control model? Wolfgang Matt's Super Star offers deep, fish-shaped fuselage, thick tail surfaces and wing, plus strip ailerons again.

Super Star is an aerobatic radio controlled model designed specifically for best performance in the FAI aerobatic schedule. The shape and construction of this model hides innumerable compromises, essential for best all-round performance.

Since the model is designed for out-and-out performance, I do not recommend Super Star as a beginners' model, although this machine can be flown over a wide speed range, while still maintaining positive control. Despite its remarkable all-out aerobatic ability, you will be astonished at Super Star's ability to fly perfectly satisfactorily without aileron control, using just rudder, elevator and throttle controls, the only modification necessary to fly in this mode being to increase the dihedral angle to 7-1/2 degrees.

Super Star has been flown successfully using a wide range of 10 cc power plants, including the Rossi 60, Webra 61, Enya 60 and Super Tigre 60 RV etc.

Now for the construction notes, which are limited to the essential points of construction, since I feel that anyone attempting this type of model can reasonably be presumed to have the necessary building ability to complete this model without much prompting.

Fuselage: Prepare the fuselage sides on a flat building board, making sure that you are building two opposite sides - not two identical! Follow the construction sketch on the plan, adding the top and bottom triangular longerons, wing seat doublers, and filling blocks at the nose including the engine bearers to make up two basic fuselage side structures ready for joining.

Naturally, every model builder has his own constructional techniques. To ensure true alignment, I assemble the fuselage directly over the plan, which I cover with plastic sheet. An alternative method is to draw the plan view of the fuselage on the building board and assemble the fuselage over this.

Assemble the fuselage over the plan upside down, laying the fuselage top deck on the board and gluing the fuselage sides to it. Use right angle to true up the sides and clamps to hold them against the formers. While this assembly is drying, construction can be taken a stage further by adding the fuselage underside sheet, grain across the fuselage for strength. At the nose, filling blocks are then added and finally the ply floor. When all glue has set, remove the assembly from the building board and add the remaining filler blocks at the front of the fuselage top deck. The fuselage is now structurally complete, and the next job is to shape it to the sections shown on the plan, first drawing the side view outline on to the balsa and shaping to this line. The fuselage is then rounded off, preferably using an electric drill and sanding disc, then finally hand sanded to finish.

Wing: The wing is best built in one piece using two perfectly true building boards set to the correct dihedral angle. It can be built in two separate halves and eventually joined using the dihedral brace, but the one piece method is to be preferred.

Prepare two sets of wing ribs using the 'sandwich' method as shown on the plan, cutting rib blanks, assembling as a block and carve and sand to shape using the root and tip templates. Next, make up the mainspars using medium hard wood, with the spar doublers in the centre.

Pin the two lower mainspars on the board and then position the wing ribs. Align the ribs using a purpose cut jig sheet placed under the ribs just ahead of the leading edge. Cement all ribs and then add the leading and trailing edge spars. The jig pieces incidentally are cut in half span lengths and cut to shape..."
