Pilatus PC.24 Royal Flying Doctor Service of Australia-Scratch build from card and foam

This model of the Pilatus PC.24 finished in Royal Flying Doctor Service of Australia was scratch built from card and builders foam salvaged from a skip,the method of construction can be used on any type of aircraft.







Start by drawing up to the size that you want,card templates is a good way to go so save those cereal boxes they are useful



Make up a balsa fuselage crutch from which will be the basis of adding the required shapes



Add nose and tail sawn blocks of builders foam



With coarse glasspaper sand the sections to shape



Add fuselage formers



Next add blocks on the underside of the fuselage infills between the formers




Now fold thin card between the nose and tail formers holding in place with masking tape while the adhesive sets



Make up the wing internal membranes from balsa sheet running a spar from root to wingtip



Use a square barbecue stick for the wing to fuselage joiner



The engines are made from balsa dowel,you can burn out the inlets and outlets with a soldering iron or use metal puches to get the internal shape then carve out with a knife blade



Making up the engine pods attached to the balsa membrane makes them easier to handle



Wheels are made up from rubber seals filled with two part epoxy,the seals are laid onto polythene sheet to stop them sticking to the building board



Undercarriage legs are made from cocktail sticks and doors from folded card

Paint is artists acrylic,for filling the foam I used Americana Triple thick brush on glaze thinned 50/50,base coat white was Blackfriers acrylic white undercoat,lettering was first painted onto tissue paper that had been treated with a thin coat of triple thick laid onto glass then peeled off when dry after the lettering was done,this was then stuck to the model with more thinned triple thick,control surfcaes were marked with an Edding 0.001 marker pen
