Spent the last number of months building a quadcopter. I though I should share the results. Great fun with a number of crashes, broken props and motors. The bottom link is a 4 minute youtube flight video.
You'll notice in the video, the first half the motors are red, but later on they're blue. In one test flight,
we lost power to one motor, the quad flipped over and did a power dive into the ground. That took out a pair of motors and props.

connect to the ESCs. The two leads on the left are for battery power.

Rana,
Yes, I should be lighter and the wiring is less likely to break from from a solder joint.
Thanks
TC,
I have a problem now of the motor mounting nuts coming lose. I'm petty sure the paint does not help.
Thanks for the head up.

@Jerry,
The paint on the ends of the props can cause a propeller to become unbalanced and increase motor vibration. If you have not balanced your props after applying the paint, you may have increased motor vibration.
Just a thought.

Rather than using multipurpose PCB for the Power system, you can use two copper clad bords one slightly bigger is size, which will result in high current handeling capacity.
These two brds can be joined with any instant epoxy, one plate can be use +ve and the other as -ve.
