Girocopter part 3: wings

Having not made wings before I had to try a few techniques to get a suitable effect that was sturdy but light. Below is the process used to make the tail section, The rotors were made in exactly the same way.

I used a card template to work out size and shape.

A wire skeleton was cut to shape for the ribs

Wide masking tape was layered carefully over the wire ribs. 

The wing was turned over and a layer of tape added to this side, care was take to push the tape over and around the wire as it was applied. This was done with a rounded wooden tool and meant the tape was flush with the wire.

A coat of pva was added to give the wing strength.

The tape was then cut down to shape, a bit like a bat wing.

Here you can see the rotor blades, same technique but thinner with more ribs. The main wire arm of the rotor extended well beyond the tape so it could slot into a brass fixing.

The finsihed tail sections. I added small brass knobs for finish  and a hooped tube to the very top through which the brass control rod slotted.
