Just received my Hubsan x4 and just charged it but it only took about 10 mins for the battery red light on the USB to turn of to indicate it's charged which I thought was a bit too short but i plugged the battery in and done the bind process which was all good and it flew good used it for 2 mins then turned the transmitter off left it for a bit then turned it back on but the remote wasn't binding so I put it on charge but the red light went off almost straight away and know won't bind? Could it be fualty or am I doing something wrong?
