This is the Hobbyking Quadcopter frame, together with the HK quadcopter control board (V1). I gave the flimsy landing gear some improvements and replaced the skids with some old (never throw anything (-: )HK-250 tail booms. Also added some CF pipes to the construction and glued it all together with some epoxy. Not good to see in the video, are the LED lights below the arms (3x red and the front one blue).
My Configuration:
* 9x5 props
* 4xHacker Style 20-28M Outrunners
* 4xHK 18-20A ESC (card programmable)
