just for the record has anyone noticed a difference when using a usb hub ? i have one (non powered) and it struggles to charge 4 helicopters at the same time! i find it best to charge directly from the usb socket on the comp. even an extension lead can affect the time it takes.
I recently plugged my usb charge cord into a house current to usb plug from a cell phone charge cord and it charges fast.
Maybe your your usb hub idea would work with that. 😀

Whew! 4 helis at one time! I don't know exactly that much about the whole usb thing, but I would never charge more than 2 from the same computer, and that's only when you have 2 banks of usb's. I wouldn't worry about the poor performance of the charger, I'd worry about how much draw and how much life your taking away from your power supply!!! The usb is designed to be able to charge one thing, and one thing ONLY. On my toshiba, if I have one heli plugged into one usb on one side's usb bank, then it won't accept any more on that side. Remember how you're not supposed to plug more than one power strip into an outlet and how even at that you're not supposed to plug more than one high-draw thing into that outlet at a time, and if you don't follow that the wires in the house heat up too much and can catch on fire, or best case fry the breaker? That's what your doing to your computer when you do that.

take the battery out and change for a new one.
I don't know if you read the first part, but that's easier said than done, and requires a second heli that doesn't fly but can charge and some fairly decent ammount of wire work to all of the batteries. There are no off-heli chargers out there for this type of battery.
Just read the first half ofthe topic and you'll see how we were trying to figure out how to do that.
I guess you could check solder joints to motherboard,however if you start messing with heli will screw up a warranty as such-RB has given some good advice.

New heli. USB takes 65 minutes for a full charge giving 5 minutes of flight. Remote Control takes 30 minutes and gives 2.5 minutes of flying. I letting it cool for more than a 45 minutes before charging. I've emailed this information to the seller. They said the manufacturer said the battery is a "consumable" item and did not offer any reconciliation. I've emailed them back reporting that the charge time states it should take 30 to 35 minutes for 6 to 8 minutes of flight according to the ad. This was bought from ebay. I am going to give the seller a bad mark since his ad was wrong. What would you do? Any suggestions? Do I have a bad battery? Charger? Heli?
Thanks for any advice.

I'd RMA it as defective if it is within 30 days. Stated reason: Battery does not hold a charge.

Actually, in that case, it's actually easier to do-you put quick disconect cables on the wires of the battery and board, then just buy annother board or take one off of a dead heli. Then you just connect the connectors on that one, then plug it in with the USB cable.
However, yes, you still need a few minutes to let the motors cool. Otherwise, they WILL fry. Either you will wear them out, wear out the teeth, or if you fly long enough, I've heard of chineese motors like these going so long that they can weld themselves together or melt solder and when you stop for the first time, they freeze up then and there.

Charging the battery out of the copter should be no different
It is different. It is dramatically different. You are changing from supply->PCB->battery to supply->battery. Until that PCB is analyzed to see if it has a charging circuit or just a pass through, this is a terrible idea. If the PCB is just passing the supply straight to the battery, then you don't need the PCB. However, there MUST be a circuit that monitors the charge in the Lithium battery and protects from over charging. If that circuit is in the PCB rather than the charger... you'll destroy the battery and maybe the charger too.
The good news is that you won't have to worry about roasting your motors.
I want to charge the battery off of the heli while flying the heli on another battery. When the heli runs low on its battery, I could do a quick swap with the battery that is charged. Would this be possible with this:
110v Charger for SYMA Mini Helicopters S107 S105 S009.

What are your ideas for accomplishing a charge of the battery off of the heli?
Thanks for any advice, Ron
