HELLO FOLKS ....

I RECEIVED A HERCULES HELICOPTER (35850) FOR CHRISTMAS, AND HAVE HAD NOTHING BUT PROBLEMS WITH IT !!
FIRST OFF, THE BATTERY NEVER FULLY-CHARGED, EVEN WITH DOUBLING THE CHARGE TIME. ..... SECONDLY, THIS HELI
HAD NO POWER TO CLIMB AT ALL, AT-BEST IT COULD HOVER FOR AWHILE MAYBE A FEW MINUTES WITH NO-BREEZE !!
TRYING TO CONTROL/ MANEUVER IT IN ANY DIRECTION WAS IMPOSSIBLE. .........ALL-SAID-AND-DONE THIS HELI IS TRASH !!!
HOWEVER, I AM TRYING TO MAKE THE BEST OF IT. THE LAST PROBLEM HAS TO DO WITH TRYING TO CHARGE THE BATTERY.
I BELIEVE THIS LIPO BATTERY WENT TO LOW TO ACCEPT A CHARGE, AND NOW FAILS TO ACCEPT A CHARGE AT ALL. .....
NOW, ALL OF THIS, AND I FIND A " Small / FLASHING-RED-LED" BLINKING ON THE CIRCUIT BOARD WITH THE POWER ON.
WHAT-NEXT ? I HAVE BEEN GOOGLING NON-STOP ABOUT THESE PROBLEMS, BUT FAILED TO COME UP WITH ANYTHING.
I REALLY NEED TO KNOW WHAT THIS RED-FLASHING LED IS ALL ABOUT. ..........

*** HELP / PLEASE, SOMEONE ADVISE ME WITH SOLUTIONS FOR THESE PROBLEMS !! ***

THANK-YOU-ALL, FOR YOUR TIME AND TROUBLE !
SINCERELY, NITRO-BTU..
