Hi (Privet) from Russia

[qvuvan]

Hi guys, My name is Vuvan, from city Saint-Petersburg, Russia.
I'm a newbie to multi-rotors and now I'm following my own project Quadcopter. But quite early got some troubles.
I'm using :
-battery Turnigy nano-tech 2000mah 3S 35-70 Lipo Pack
(http://www.hobbyking.com/hobbyking/store/__11944__Turnigy_nano_tech_2200mah_3S_35_70C_Lipo_Pack.html)
-4 motors NTM Prop Drive 28-30S 800KV/ 300W Brushless Motor (Short Shaft version)
(http://www.hobbyking.com/hobbyking/...00W_Brushless_Motor_short_shaft_version_.html)
- with 4 ESC Turnigy AE 30A Brushless
(http://www.hobbyking.com/hobbyking/store/__11617__turnigy_ae_30a_brushless_esc_.html)
-Controller Seeeduino v2.21
The ESCs are armed when I set the value of range 17 to 56.
I went through some experiments by setting a constant value to the ESC. (like servo.write(57) ).
After several times that the motors were rotating, they slowed down then stopped completely. And now even the ESCs do not sound any sound "ping..." when being plugged to the battery. I already recharged the battery but the same thing happened.
is that really a problem with a battery (in other words, I had bought a FAKE battery) or that I should do something special with setting values to ESCs?
Please help me. And thank you very much!

In addition, I use the charger Turnigy Lithium polymer 2S/3S charger: http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=7637
Does it go with the battery??

Aye Up qvuan. Welcome to MRF. If you can wait tim June Ill help you out personally as I am supposed to be visiting a friend teaching english in St.Petersburg!

Anyhow do you have a voltage metre to see what the voltage is in the pack?

I dont know the components you have but I am sure some one on here will chip in to help.

WOW, hi Droider, I REALLy want to see u here :tennis:. How nice it is! And thank you for replying.
By the way, unfortunately I have only an analog voltage metre so I cannot see a change of the voltage in the pack. It always shows out 11-12V.
(The pack is not completely empty 'coz it still feeds the controller).
Yet, I'm really looking up for someone here to help me figure out whether the problem is on the pack. Or maybe because of the charger. I said I charged the pack once, but perhaps it was not charged at all by a wrong charger.
