Quadcopter Prototype

My first project is a quadcopter (prototype pictured). The frame is made from 3/4" aluminum square tube. The proto breadboard in the center has the accelerometers and gyros (IMU 6DOF Razor), the Magnetometer (HMC5843), and breakouts for the 4 speed controllers (TURNIGY Plush 30amp Speed Controller). The four motors are Turnigy 2217 16turn 1050kv 23A Outrunners with APC 12x3.8 standard and 12x3.8 pusher props. Not connected in the photo is the ZIPPY Flightmax 4000mAh 3S1P 20C battery.

Here's a closeup of the power distribution. I'm still working out options that are lighter but for now this should work for prototyping. With each motor pulling up to 20Amps times 4 for a total of 80Amps I needed some pretty beefy power distribution. The wire is Turnigy 12AWG which has very high braid count for more amperage capacity. I used a terminal block (available at Home Depot) and terminal wire connectors.
