THE construction is perfectly straightforward, but the following notes, while not stage by stage instructions, will assist the less-experienced builder.

Wings: The ply ribs are made by the sandwich method. 8 BA clearance holes are drilled at the dowel positions so that ply strips can be bolted together for shaping. One of these ribs can be used as a template for cutting out the balsa ribs. The wing root facings are similarly made, locating the hole positions from one of the ply ribs. The holes in the ribs are then enlarged to accept 10 SWG aluminium tubes and those in the facings to take 10 SWG piano wire. The ply ribs are then as-sembled on the tubes and the wires and the leading and trailing edges added. Araldite is used to fix the tubes in position. When set the wing halves are slid off the wires and completed in the usual manner.

The tips should be added before sheeting the leading edge and must be very securely cemented. When complete the wing halves and centre piece are slid on to the wires and sanded down as one unit, so avoiding any unsightly ridges at the wing joints on the finished model. Cover the wings with heavyweight Modelspan and give one coat of dope and three coats of 50-50 dope/thinners.

Tailplaone: Assemble the leading edge, trailing edge and straight ribs. Add the geodetic ribs, half notching where they cross. Cut the spar slot in the geodetic ribs after assembly. Cover with Jap tissue and give three coats of 50-50 dope/thinners.

Fin: Build the 1/8 x 1/4 in outline and add the 1/4 in sq spar. Remove from the building board and add the 1/8 x 1/16 strip ribs. Fill in between these strips with 1/8 x 1/16 to bring the spar flush. Sand-paper to a streamlined section and cover as tailplane.

Fuselage: Cut cut the 1/4 in sheet nose core and add the 1/4 in sq hardwood pieces, then the longerons. When set, add the fuselage sides and wing mounting block. Carve the block to accept the wing centre piece and cement this in position. Care must be taken to ensure that the wing centre piece is correctly aligned on the fuselage. Add the 1/8 sheet nose doublers and when set, carve and sandpaper fuselage to shape. Cover with lightweight Modelspan doped on, give two coats of Belco Primer Surfacer, sanding after each coat and finally one coat of coloured Belco.

Trimming: Add nose ballast until the model balances at the rear spar. Pin the auto rudder straight and adjust the tail inridence until hand launching gives a straight glide, just approaching the stall. Use the auto rudder to obtain a right hand circle of 150-200 ft diameter, when launched off the towline. Use a dethermaliser on every flight. A clockwork timer is recommended as it can be arranged to start when the model is released from the towline."
