Hi Everyone,
My quadcopter configuration
FRAME : Q680 V3
LIPO BATTERY : Turnigy 2200mah 3S 20C Lipo
MOTOR : Multistar 2216 800KV 14-Pole Outrunner Motors,
ESC : Afro 20A ESC,
FLIGHT CONTROLLER : KK 2.1.5,
TRANSMITTER : FlySky FS-TH9X-B
LANDING GEAR : Lightweight FPV Multifunction 200mm High Landing Gear Set for Multi-Rotors (Red/Black)

My quad drifts away after taking off.It is not stable or in other words,the quad is moving away just as it likes.Is there anyway that I could solve this problem ?

Use a flight controller with GPS and fly in position hold mode.

To elaborate, any quadcopter that does not have GPS tends to drift. They require continuous manual inputs to maintain position. However, if it is drifting in the same direction all the time, repeat the accelerometer calibration with the quad PERFECTLY level or use the acc. trims on the kk 2.1.

After drifting,I slightly increased the pitch and the quad moved forward and to stop I decreased the throttle.Just banked front when landed.The drifting is the problem.

@Sukhpreet,
I did ACC. Callibration
Did ESC Callibration ( But in reality,this is a rebuild.Means I removed all the components,disassembled the frame and everything.Then started over with new Tx )
Don't know how to connect to PC.

Get a cable.Download the software from net.Its freely available(Thats easier Smiley ).

And connect. Smiley Or refer the manual. It must be having any way to set all the joysticks/sub trim  to 0 value. Its having the display as well, So you may not even need to connect it to pc then Tongue.

No youtube is blocked in my company...

if the quad is banking right, check the PI settings... set it to default or the values given in the previous post.

Increase your altitude. You are probably still in the prop wash. Some amount of drift is normal but that is quite a lot. Use your radio trims, or preferably the accelerometer trim on the kk 2.1 to keep it level.

It definitely looks like prop wash effect...keep it at higher Altitude, and fly it...and use tx trims if it drifts
