First you need to create a paper template. I used A4 white paper. I drew my lines for the angles of the wing shape on it. Including fold lines for the aerofoil shape.

Second you need to map the paper template across to the card you wish to use. In my case black card. (handy hint here is that pencil shows up when viewed at an angle with a light behind.

Thirdly you need to make your cuts and folds for the wing shape. For this I used the edge of the table and a strong flat ruler.

Once your cuts and folds are made for the upper and lower part of the wing you will need to stick the wing sections together for this I will use black gaffer tape as for me it has the right strength, weight and sticiness balance.

Once the wing is complete you need to add cross members to hold the structure.of the aerofoil These should be cut out of paper card with addition folding flaps for mounting with a minimum amount of PVC glue.

At the tip of the wing a stabiliser will be added. This should be made out of folded card and shaped like a teardrop with the option for a rtudder at the back.

Once the wing tip has been sorted. You will need to add a mount to the thick edge/root of the wing. This is to affix the wings to the central box setion or aerocore(tm) There should be a few of these and these will need to be cut through with a hole in order to be able to attach via dowling or a straw to the central areocore(tm). Create in the same method as the cross members in step 5.

Now to create the aerocore. This should be made out of stiff cardboard for lightness however plasticated card would be a better option. With slight weight penalties. The inner areo core should be made out of card. This should be folded around your engine in a stiff box section bonded strongly at the corners with tape or glue.

Now to create the outer aerocore which will allow the inner aerocore to swivel along the central axis along the wings. This should be done in the same way as in step 8 however it needs to be just slightly larger to envelope the central core.

Now for the swivel mechanism. The inner core will need to be slight bent to accomodate itself in the outer. on the outer cut a hole which should be reinfored as minimally as possible. The inner core will have some stiff cardboard tube cut and stuck onto the side in the correct area in order to allow the swivel. The hole should be the same size as the tube to make it relatively tight fitting. Once the cuts are complete then glue the tube on and match it up with the hole squeezing it together so the inner core sits within the outer core. Your engine/motor can now be attached to the inner core.
