Here's my custom made "pocket" quadcopter. Flying weight is 5oz with a 1000mah 2s battery. The frame is made from basswood strips and carbon fiber. The frame weights only 2.3 ounces without the battery, and has LEDs for night flying and orientation. The motors are C-10 micro 8g 2100KV spinning GWS 5x3 three-bladed props. The ESCs are 6 amp hobbywings.
