This is a quadcopter that launches rockets. According to Scottsdale, Ariz.-based ukarmy04, the Flitetest forum member behind the project, it's more of a proof of concept than anything else. The body is mostly wood, with electrical parts from kits, and has a few novel features. The first is a metal disk at the center to absorb the rocket's blast. The second is a pair of central copper strips that connect the motors to the battery. The motors and batter are mounted on the bottom of the drone, as far from the rocket's blast as possible.
