Plane building in styrene 101:
Here is a short description on how to build small scale planes in styrene.
Materials needed:
- Styrene (rods, strips, Sheets) evergreenscalemodels.com
- Sharp scalpel
- Sanding paper, fine modelling files (rounded, curved)
- Paints, modelling glue and thin filler (for example Vallejo.
- Decals in 1/300 or 1/285 scale
- Removable adhesive (re-mount sprayglue or glue stick – For glueing profil templates onto styrene and be able to remove again)
- Small drill 0,70 mm (for mounting hole in the nose and for holes for struts and landing gear
- 0,75mm piano wire (for nose mount)
- Tweezers
- Vernier caliper (for taking and transferring precise measurements from scale drawing to the model).
1. Scale drawing
Find a good ressource on the model you want to build. You will need a good 3-view line drawing, preferably as a file. If in a physical book You will need to scan.
1.1 In a drawing program (Adobe Illustrator or the like) use the 3-view drawing as a background layer and make a line draving on a top layer. Scale the drawing so it will print in the desired scale. Put in measurements on critical measures. Check the measurementson the drawing after printing!
An example of a drawing for some up-coming DH-4 bombers:

On the pic- NOTE the top 4 sets of plane components. Use thos to build the plane as follows (the bottom parts of the drawing are measurements and reference):
1.1.1 make 3 sets of prints:
use one as a building reference.
Use another for making the wings and tails
Use the third for the fuselages
Wings:
1.2.1 From the printed drawing: Cut out the entire area with the wings and tail units from the print.
1.2.2 Use the re-mount removable spray glue to mount the wing/tail cut out on a 0,3mm sheet of styrene.
1.2.3 Cut the wing profiles along the outer edges with at fine point scalpel. Do the same with the tail units.
1.2.4 Drill holes through the wings for struts at the marked points using the 0.70 mm drill. This can be done by holding the drill in the hand and spinning it with your fingers. Remove grates and sharp edges with very fine sanding paper
Fuselage
1.3 Cut the side view outline minus tail and landing gear out from the drawing.
1.3.1 Use the spraymount to mount the cut.out outline to a piece of strip styrene of a sufficient (but not much more than that) width (http://www.evergreenscalemodels.com/Strips.htm#Dimensional%20Strips)
1.3.2 Use the knife to form the fuselage in the right shape. Scrape off the paper outline from the body. Make corrections by estimation and by taking measurements from the reference drawing with the Vernier caliper and transfer the to the model. Gradually remove material, first with the knife, then with files and sanding paper.
1.3.3 Top down view. Start removing material senn from the top. At times placing the fuselage on the scale drawing for reference and also by measurements with the caliper. And off course -Use your judgement.
1.3.4 Make a notch in the bottom of the fuselage for recessing the bottom wings if nessesary. Make a recces or notch for the elevator if neccesary.
1.3.5 Drill a 0.7mm hole in the nose for the nosemount
Mounting the wings:
1.4 Glue the bottom wing to the fuselage. Check the angle from above and adjust.
1.4.1 Make a small block for monting the top wing on the fuselage. Make shure that the area on the fuselage for mountin is flat. Check height. Glue the block to the fuselage. This looks OK when the wing is mounted close to the fuselage. If the wing is mounted high it looks betre to make ALL the struts. But it is slow going.
1.4.2 If the wings have dihedral – Bend them gently into shape
1.4.3 rougly cut out pieces for the struts from very fine strip styrene. (or heat streched sprues from a model kit)
1.4.4 Glue the struts to the under wing. It is OK to have excess length. This can be cut later.
Mount the top wing by guiding the stuts through the holes and glue the center of the wing to the block.
1.4.5 When the glue is completely dry: Cut off excess struts that rise above the wing.
1.4.6 Mount the tail units
Undercarriage
1.5 This is the hard part.
1.5.1 Make 2 small V's by gluing 2x2 fine pieces of strip styrene.
1.5.2 When dry. Cut the excess length to the rigth measurements.
1.5.3 Glue the V's to the fuselage
1.5.4 Before the glue dries cut out the axle beam in the rigth length (I often get this too long, having to remove it to avoid the plane getting a squatting appearance). Glue the axle to the inside of the pointy ends of the V's
1.5.5 Make slices of a styrene rod for wheels. If you dont have the rigth size you can gently heat stretch the rod over a candle.
Now you (perhaps after a couple of tries) should have something like this:http://cf.geekdo-images.com/images/pic682790.jpg
Use the thin filler to even out different rough areas.
The if you want you can add details: Machine guns etc.
Don´t go overboard with detailing. It is a game piece after all. This one went a it too far (all the cylinders of the rotary is there) link
For planes with rotary engines we make the front end of the fuselage with a round rod and the rear with a beam. The seam is covered with filler.
Then add a nice paint sceme and decals:
