These are getting more and more popular. I think with Ben's skills, and his CNC machine, he could build a pretty good FPV (first person view) quadrocopter. It would require building the copter, adding a camera to it (like this one) http://www.hobbyking.com/hobbyking/store/__13438__900MHZ_200mW_Tx_Rx_1_3_inch_CCD_Camera_NTSC.html
and then modifying an rc controller to add the LCD screen for the FPV view.
