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.
need more details like which firmware is used?
what is the PI settings?
@ VTOLkarthik
KK2.1.5
HW Ver 2.1
FW Ver 1.9S1

Found this when the KK powers up.

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.
looks like the PI settings is not the right one. Am right now in work, will check the values what i had used in mine. Meantime you can check in youtube for the right or default values.
I will be doing a test flight after 5 o clock.Will check at that time.
Taking xtra lipos to playground

have you checked that everything is ok and sub trimed in Receiver test?
1* Acc calibration....
2* Esc callibration
3* Connect tx to pc. Set all the values of joysticks to 0(and sub trims to 0)
save it.
4* Go to the fields, Fly ur quad(and u need to set sub trims(on tx) to adjust accordingly as per the wind)
@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.
with flysky, you must have got a cd and a cable
install the software from cd, connect ur tx to pc via that cable. and see the tutorial regarding this :)
@Sukhpreet,
Just received an RF Module ,A Receiver and A Transmitter
Bought from Robu.in
It was already said in Robu.in's page
Dear Zalman
use these settings and share the video
Pgain alleron 60 45 40 30
Pgain elevator same
Ruder 75 20 30 10
happy flying
Get a cable.Download the software from net.Its freely available(Thats easier :) ).
And connect. :) 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 :P.
Is the stabilization mode activated?
And did your check on gyro bubble?
@kiran rc,
Gyro Bubble is correct in the CROSS HAIR LINES ( Don't know it's name ).
Also the quad was tested by enabling SELF LEVEL Function
Another video of my quad.With HIGH I-GAIN
https://www.youtube.com/watch?v=Hwi6_OvI-9E
I am not able to check the video,
try with self-level off and try flying...
@VTOLkarthik,
If you are using a Mobile/Tablet to browse RcIndia,the videos Uploaded through YouTube can't be seen.So just click on the video were the error is written.
@VTOLkarthik,
Also my quadcopter banks right when disabling the SELF LEVEL and eventually the props will hit the ground.
https://www.youtube.com/watch?v=W-VJBCkHNOI&feature=youtu.be
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.
HI guys,
I tuned my Quadcopter ( PI SETTINGS ).
Now here it is :

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.
Try using trim buttons on the tx... 99% itz gonna work
It definitely looks like prop wash effect...keep it at higher Altitude, and fly it...and use tx trims if it drifts
At that altitude such drift is normal
@Sooraj.Palakkad,
So I have to keep my quad at a height more than that in the video ?
@SK1701 & VTOLkarthik,
What does PROP WASH EFFECT means ?
Prop wash means a twisting air flow in the helical direction, which is commonly seen when it is taking off.
it creates an yaw force which is what is seen in the video. Kindly google for more info and the effects of it. :)
Hi guys,
Today I went to the field and did a test flight.At last part the quad fall down .Then I found out that the motor was loose and it was moving around.Three screws were not under the motor.Somehow gone.
https://www.youtube.com/watch?v=k1h-tQIo7SI
Your video is private.
To prevent vibrations from loosening the screws, use a threadlocker like Loctite or Anabond. Make sure to use the BLUE version as it is removable where as the red is permanent. Also, use no more than one drop per screw or else you will not be able to take it out. Use it only for metal-on-metal contacts as it will corrode plastic.
@SK1701,
Accidentally the video was enlisted as PRIVATE.I have only RED Thread Locker.I couldn't find BLUE anywhere.
Good fly... u can also use zip ties or cable ties...suits best when it crashes...
btw be careful on the transmission lines..!
Very bad news guys................
My quad fall from a height of about 20 meter to the ground.The crash was due to the M2 mototr.Suddenly it stopped and the quad leaned to that side.
Also the quadcopter at that altitude was drifting rapidly to the left side.I couldn't stop it.Nothing was damaged.Only the Nylon screws joining the Landing gear and the frame was broken and there is a slight crack in the propeller.
The video of the quad is only upto 46 Seconds.Forgot to shut the camera and I don't know how to edit and doesn't have anything to edit.
https://www.youtube.com/watch?v=JMfvltPlfNM
Was it drifting continuously leftwards ? Or you were giving roll input ?
If it was not your input , try trimming roll to right.
By the way, editing options are available in YouTube itself.
Also , kk board can't make the craft to hold a position , however you tune or perfect the settings , so continues corrections from user is necessary to make the craft hover at a fixed altitude and spot.
For this you need practice , Its just like learning to drive , so fly everyday and develop your skills .
For a start , try to make the craft hover at a spot in a fixed altitude .
Hey Kid,
its a very bad sign of an youngster like you selling faulty RC stuff.
We encourage people to experiment on new things. but not to sell the faulty stuff if u failed in it..
I trusted you and bought these items coz ur in need of money to purchase NAZA m lite. But then U ended up cheating ... :salute: :salute: :salute:
Finally you blocked me on whatsapp and added my number to auto rejection.
As a good sing of a trade. I only request you to take back the faulty items.

@Sooraj,
Yes.The quad was drifting FORTH continuously.And I didn't changed the Roll & Pitch.Really the video is taken from the back of the quad ,so don't think that the quad moves left.It is going FORTH.
What is the orientation of your copter ? I thought white arms are back side .
Is it X type or +type ?
@Rc Foam makers , please specify what went wrong .

Zalman had a set of 4 * ESC and 4 * Motors combo brought from some Chinese website and they are not fully functional.
I found them defective as soon as i opened parcel and inform him about the same, asked him to accept the return.
last night he said we shall discuss about it and later this morning he completely block me on whatsapp and not picking up the call.
This is MULTI-ROTOR section and not SALES section..........
Grow up my kid < zalman15320011351 >.. Take back your stuff..
If it is so, too bad Zalman. Don't cheat anyone. If anything went wrong, accept it.

This happened to.my quad also...it turned out everytime i did the Acc calibration the landing skids were on...after a while i calibrated the acc without the landing skids and thw quad is now very steady probably the landing skids do not make the quaf completly flat. ..maybe you can try this.
