Description
This is a quadcopter design that uses the folded aluminium bars from a fly screen as the arm struts.
Note that the motor mounts are designed for a spacing of 42mm diagonally between the motor mounting bolts. This is parametrically adjustable.
A bill of materials for my build is available here:

Total weight is 906 grams, with a 2200mAH li-po battery. I have 400 grams of steel strapped to the bottom as a dead weight. It can fly for about five minutes with that load.
