I've recently damaged a Hubsan Quads X4 by hitting a cable with it and it fell hard about 30' onto an asphalt parking lot. It landed upside down and the blades were turning wide open, so I had to disconnect the power wires to shut it down. After that when the power wires are connected the blue LEDs blink alternating left and right, then when the transmitter is turned on they blink together. The transmitter LED turns green saying they are communicating, but the copter won't respond and the blue LEDs keep blinking. Can anyone tell me if there's a way to fix whatever is wrong? Also, I don't have whatever it takes to make the camera work. There's a slot to insert something but I don't have it, and if it came in the package I accidentally threw it away without ever seeing it. Can anyone tell me what to get in order to get the camera working, and also if there are any tricks I need to know about? Thank you for any help! David
It sounds like you may have damaged some components on the flight control board....I think the blinking is correct except that it is not binding. When it binds, those lights should stop blinking. As a non-techie, all you can do is look at the obvious things like making sure the motors spin freely by hand, etc. The slot probably holds an SD card - that's a tiny memory card that holds the photos and videos. Here is a guy with a similar problem- you may have to replace the main board: http://www.helifreak.com/showthread.php?t=599591
