You must tighten the two screws that secure the switch PC board. This will mcure the "dropout" that you, and others, experience. I am an elctronics engineer and it took me almost a month to remedy this!
Having the same problem, something with the reciever or transmiter. Flown about the same 10 times, this just started 2 days ago and had it a month or so. The s032g are not UBS charged. I put new rechagable batties in the controller, nothing, took it apart nothing, unraveled the reciever wire a little (3") and got it going then this morning same problem. I am going to open it up and inspect the reciever to see it the wire came loss. I think it is the transmiter, it seems to happen when lowering the throtle, yellow lite on heli blinks and comes back after drop throttle to 0.

You're likely doing one of two (or three) things:
Undercharging. Make sure to charge until light on charging unit is fully bright. If the light on the charger gets ANY brighter when you unplug the helicopter, then it's not fully charged. Note that if you are using a usb charger, that most laptop usb ports and front side desktop data ports are not fully powered to the required 5volts DC, and so can take several hours to fully charge the battery.
Over-discharging. Once you cannot maintain altitude, land helicopter and power it off. Draining a Li/Po battery fully, or even close to it, will weaken it's ability to hold a charge, and can ruin it entirely. Not like the old Ni/Cad rechargeable batteries.
Improper care. Batteries should be allowed to cool for 10 minutes after every flight, and 10 minutes after every charge. Like over-discharging, overheating will always weaken, and can destroy your Li/Po battery.
hope this helps let me know
