So #2 was designed to hover higher and thus be able to tackle things like carpet or concrete on launch.
It does this OK. Once it is going it is fine, launching it is hard on rough surfaces, but it goes far better than #1, especially for it's size. It has a greater range of speeds that it hovers at, but the fins at the back make launching interesting
Step 1: Materials and requirements
Scissors or knife (ruler to help if you use a knife)
Glue (white or stick-form)
Step 2: The Template
For those who need to know, bold lines are cut, dotted are fold. Heck, for this model it doesn't matter which way you fold, as long as you make two opposite sidewalls.
Print it so it is 8-9cm across. If it's bigger, then you'll need more than a paper-clip at the front. If it's too small then you'll need to find a smaller clip, or possibly use a staple. Remember that the bigger it is the better it flies, so don't go make a really really tiny one.
