Ghost SingerFUSELAGE
Ghost Singer was originally designed in 1986 for the proposed 2 metre rules which were to include a speed task. The model was influenced a great deal by Sean Bannister's Algebra which was kitted by Ripmax in UK. It not only makes a fine competition model but can simply be flown for sporting fun. It flies like an arrow with an excellent glide angle and is great on the slope. This model has 2 channel functions: - rudder and elevator.

CONSTRUCTION WINGS
The wings are fully sheeted and are made in two halves joined onto wire rods through the fuselage. Cut out two sets of ribs. I used the sandwich method to cut mine however individual ribs are all drawn out on the plan. Pre-join the balsawing sheeting for top and bottom. Accurately trace the spar, rib and false leading edge positions onto the bottom sheets. Glue the bottom main spar onto the bottom wing sheet and pin it down onto a flat building board. Add ribs onto the spar and pack under the bottom sheeting to mate with the entry curve of the ribs near the leading edge. Glue the top mainspar, false leading edge and vertical grain webbing. Glue in the hardwood blocks for wing retaining cup hooks. Glue the brass wing rod tubes with epoxy. After the epoxy is set crimp the ends of the tubes. Now is the time to decide whether or not to include 3 degree wash out into the wing. Wash out will give the model slightly improved stability but without it the speed range will be greater. If wash out is to be built in pack up the trailing edge towards the tip then glue on the top sheeting. Otherwise keep the wing flat on the building board and glue on the top sheeting. Note the trailing edge is formed by mating the top and bottom wing sheets which is then sanded to a fine edge. Fine fibreglass cloth between the sheeting would give a really sharp edge if desired. Add the leading edge and wing tip blocks, sand to shape. The wing tips curve from the underside to meet the top surface which is kept flat to give an "anti slip" airflow around the tip.

FUSELAGE
Cut out the fuselage sides from balsa sheet and reinforce the inside faces with plywood doublers. Accurately drill the holes for wing tubes with fuselage sides clamped together for exact positioning on both sides. Add the triangular balsa longerons. Cut out all formers in preparation for assembly. Glue the formers onto the fuselage sides starting with F3, F4 and F5 then drawing the front and rear ends together onto the rest of the formers. A fuselage jig would be very useful for this stage of construction to keep things straight. When set, sheet the bottom of the fuselage cross grained for strength. Make up a ply canopy/hatch cover with locking tags or tie down screws at both ends. Add noseblock, sand to shape. Insert a lightweight nyrod for elevator and closed loop system for rudder control. Sheet top of the fuselage. Glue in the servo rails and hardwood block for the tow hook.

TAIL SURFACES
These are cut from 5mm balsa sheet. Careful selection of the lightest weight timber is essential here. Taper the rudder and elevator and add hinges. Add the wire elevator joiner. Set the fin onto the tailplane at right angles. Glue these onto the rear fuselage and add the fillets at the fin/tailplane joint. Glue the ply tail skid into place. Lightly sand the entire model with fine grade sand paper in preparation for covering.

COVERING AND FINISHING
The Ghost Singer can either be covered in tissue and dope the painted, or can be covered in iron on plastic films. I chose the latter for mine using yellow film overall with dark blue trim stripes. The canopy area was painted black. Screw in the tow hook.

Ghost Singer 2FINAL ASSEMBLY
After installing the R/C gear and battery check the CG which should be around midpoint of the wing (50%) at the fuselage. The wing assembly is easy but first you must bend the wing joiner to give a dihedral of approximately 30mm at each tip. This can be done by trial and error before the wing is attached to the fuselage, make sure both joiners fit properly in their respective tubes. Screw some small cup hooks into the end ribs where shown, making sure that they line up and fit into the holes in the fuselage. Slip the wing joiners into the fuselage and slide on the wing panels, hook a rubber band between the wing retaining hooks, clip on the hatch cover and the Ghost Singer is ready to fly.

FLYING
Ghost Singer has proved to be a great performer, both as a thermal machine and as a slope soarer. It is stong, has great penetrating ability and an excellent glide ratio. This model is capable of high speed winch launches and is also suitable for hand launching. It is highly manoeuvrable and has light wing loading yet is capable of high speed especially with additonal ballast. Ghost Singer is easily transported in a small sedan.
