Obviously you can play with the design depending on what materials you have lying around, but this should give you a rough idea of what direction to go...
Date Made: June 2013
Approx Cost: £0 (recycled materials)
Approx Time: 0.5 to 1 hrs
Step 1: What You Need
*some fairly stiff plastic (I used the packaging from a roller blind)
*a big thick elastic band (I used one about 200mm long)
*a picture hook
*a piece of dowel (I used the adjuster from a venetian blind, which already had the hook screwed in the end)
Tools you need are:
*some extra strong glue
*a hacksaw to cut the wood (I used a dremel)
*scissors or knife to cut the plastic
Step 2: Make Propellers
Next fold them on an angle about 30mm from one end as per the photo.
Make them both match.
Step 3: Make Main Body
Cut a slot in one end almost the same length as the fold line.
In the other end cut a small hook along the same plane as the slot, that way the propellers wont catch on the body when released. Make the hook small, but check the elastic band will latch on to it. If this is too big, it will catch on launch and misfire.
