i too have a bunch of symas. just got the 033g and the charger lights never go out or change color. i just charge for an hour then fly for 7 minutes. love it! had a receiver issue as the chopper would cut out every 3 seconds and be totally unresponsive. searched the net for hours and saw many had the same issue. turns out the antenna wire should just dangle. DO NOT WRAP IT AROUND STRUTS OR ANYTHING ELSE. problem solved. did u find any issues other than battery charging? oh, also let it cool down for 15 mins before charging, and after charging before flight.
