I like it, that it's small, and easy to operate, so I don't want to use any external batteries...

edit: If I plug it in and try to charge it, the voltage on the battery circuit goes up to 4.10V, but the actual battery does not do anything...
The camera stops operating when the battery voltage delivered to the circuit board drops to about 3.7V (nominal) based on some early testing with the earlier #11 camera, so it's no surprise your camera will not turn on.

If sounds like the charge management IC is functional, but some chargers will not attempt to charge a lipo if the detected battery voltage is too low (overdischarged), which yours is, and probably the reason for the flashing LED. You may have a defective battery protection circuit board (the little one soldered to the battery tabs inside the tape). You could also have a battery that is shot from being over discharged. You could do some troubleshooting by removing the small charge protection circuit board and trying to charge the battery without it. That could tell if that protection circuit board is the problem, but if the camera is new, you should be able to get a warranty battery replacement.

After testing the #16 a long moment, the #11 wanted some aerial action again.

A friend lended to me his Infinity (hype wow, ripmax blaze same models) for the occasion

#11 is often over saturated but does nice videos, today it caught some sun rays piercing the clouds

Ok, thanks. I'll try to charge it with an external battery charger just for this time and I'll let you know if it works.

I think there is also another problem. I charged the battery, but it still didn't turn on. Now I tried to solder the wires directly to the battery (w/o the protection circuit), but it still doesn't want to turn on.
I connected the battery to a led for some minutes and tried to charge it with the usb cable, and it charged the battery perfecly. It just doesnt wants to turn itself on. I also tried to reset it and webcam mode, but still no response from the cam. I pluged the memory card in PC and the folders are also not there.

Any other suggestions how to fix it?

Did you try to power it with the 2-wire thin external USB power cable (NOT the 4 wire standard USB data cable)? Push the reset button with that cable plugged in as well. If that didn't make any difference, I'd see if the camera will flash in new firmware (see post #3 for link to firmware files), and if not, ask your vendor for a warranty replacement if it's a new camera.

Urgent questions!

It would be great if you guys could answer these ASAP since I need to order the camera to have it in 2 weeks.

I am a proud owner of the low-res keychain spy camera (the $9 one) and have attached it to rockets reaching 5,000ft.

A few months ago I caught wind of the #11 camera that is 720p and about $40

I have now seen there is a new #16 camera which is 720p and a new 1080p one.

Can someone explain to me what the difference between the #11, #16, and the 1080p one are? Mostly the difference between the #11 and #16 and what most people prefer.

Last question, are there any "reliable and widely-known" sellers in the original post of this thread and others with updates that are based in the USA that sell either the #11, #16, or 1080p one?
If not, who is the fastest of the Chinese shippers or the most widely-used by members of this forum which we know has the best product with the smallest chance of there being flaws or defects?

Really appreciate it guys!

The #16 is the best of the three by far.. Mine took about 10 days to get to Michigan. What ever you do don't get the 1080 unless you want to buy mine.. And to be honest I couldn't with a clean heart sell it to anyone..

I guess Tom will forgive you this time for posting a #3 video on a #11 thread

Since you have odered a #16 (good choice), now is the time to catch up on the latest news on this great camera on the #16 thread.

Since you already have a #3 you will already have a card that will work well with the #16, but should you buy any more cards for the #16, make sure they are Class 4 and not above. High capacity Class 6 and especially Class 10 are mostly not compatible with the current firmware. All this is discussed in detail in the #16 thread. As usual, all the important posts are linked in the first 5 post. I don't know how hard your rockets hit the ground, but this could be problematic for the CMOS lens assembly which is pluggable in the #16. It would have been wise to order a spare lens assembly together with the camera.

F.Y.I. all the information you just got is freely available in posts 1 to 4 at the start of this thread, free to all to read, and it would have saved you a lot of typing, and having to part with your bestist Video.
