The Tyldesley "chuckie" is a lightweight hand launched glider capable of good flight duration. It can be flown indoors by trimming to fly in tight circles or flown outdoors on a calm day.

The model is made from wall insulation (blue foam) cut with a hot wire, it could be made with 2.5 or 3.0mm balsa and sanded to an airfoil section. Balsa could also be substituted for the doublers.

Use a clear glue or white PVA glue. Children should be supervised at all times during construction.

1. On the curved sheet. Mark a straight line 5mm from the leading edge of wing. The leading edge has a black mark.

2. Mark a line 75mm parallel to the first line in step 1. This now forms the wing, mark out the other cutting lines (refer to drawing) and cut out the three wing panels. Mark the wing centre line but do not cut.

3. Lightly sand the wing joints to form the dihedral, glue and allow to dry.

4. On the flat sheet mark the cutting lines for the tailplane, fin, tail seat and fuselage doublers, then cut out. Mark the tailplane centre line but do not cut.

5. On the 1.5mm balsa sheet, cut a taper starting 160mm from the front and finishing at the rear leaving a thickness of 5mm.

6. Glue the foam doublers and tailplane seat in position and sand to a flat edge where the wing and tailplane meet./p>

7. Glue the wing centre line to the 6mm wing seat.

8. Glue the tailplane to the fuselage.

9. Glue the wing onto the fuselage parallel with the tailplane.

10. Glue the fin square with the tailplane.

11. Mark a position 35mm from the leading edge of the wing on the underside, this is the point of balance.

12. Place modelling clay or similar on the nose of the model until the model balances on the mark in step 11.

13. Test glide the model, aim at a spot 20m away on the floor facing into the wind, launch the model smoothly and observe the glide. If the model dives at the floor remove a little of the modelling clay. If the model stalls (raises its nose sharply) then add a little more modelling clay.
