hi guys.
i have a problem with my cx 2 i just purchased it about a month ago. and now it seems like i only get a minute of flight before the battery dies... than it will only hover like 4 feet of the ground and when i push the rudder it just drops to the ground and then will pop back up to like about 4 feet.... it does this with both batteries. so i am just curious if it could be a problem with the batteries or the charger or maybe the 3in1 unit itself? thanks in advance.
