Check if motors are spinning in right direction.
Props seems OKAY!

yes all r connected right direction.

Post by: Darshan for multirotors on April 30, 2015, 11:38:55 AM
Check again... check if the motors are spinning in the correct direction and if the right prop is on the right motor. .. I think this has to be the reason why it is not lifting off

What Voltage are you getting from that battery at fully charged state?


Title: Re: Help on quad copter
Post by: jeet8066 on April 30, 2015, 11:45:20 AM
11V


Title: Re: Help on quad copter
Post by: meet2ami on April 30, 2015, 11:50:20 AM
Are you using a 3S lipo? If so the full charge voltage for 3S lipo is 12.6V. 11V is too less!!


Title: Re: Help on quad copter
Post by: Darshan for multirotors on April 30, 2015, 11:52:16 AM
I suppose 11.1v is 3s

Run the props (be careful)just put tour hand under and above the running prop.. if the amount of air is more on the upper side.. The prop is wrong

@jeet8066,
Another member had a similar problem recently.
On looking at his video carefully, i found that the airflow was upwards!
The props were pushing the quad into the ground!
Normally it should show a tendency to lift near half throttle.
No way you can use full throttle without hitting the roof!

Your prop position appears correct.
Check that front left motor runs clockwise when seen from above. I suspect it goes anticlockwise!

yes ... assuming that the white are the back and the black are the front, you have the props set-up in the opposite direction

yes ... assuming that the white are the back and the black are the front, you have the props set-up in the opposite direction

May I differ?
Irrespective of whether white arms are front or back,
Top left prop is clockwise, ie correct.
Motor may be CCW, ie incorrect.

Assuming that in the photo, 'Front' is either to the left or right side of the photo.

yes, its all a matter of perspective . let the OP confirm it i guess..

Guys share me ur mail id i will share u video.


Title: Re: Help on quad copter
Post by: IndianHobbyShop on April 30, 2015, 01:01:06 PM
Jeet, don't just go by the specs. 11.1v is the nominal voltage for 3S LiPo Packs. While at fully charged state it would be about 12.6volts.

If you have a multimeter or a LiPo Alarm then please first charge the battery to the full and then measure the voltage.
If the voltage that you are getting is substantially lesser than 12.6 volts (11V is way too low) then the reason of your quad not being able to leave the ground would be a Discharged/Damaged battery which happens when people allow LiPo packs to get fully discharged.

Please confirm.

@jeet wouldn't it be better if you put the video on the page itself(as you have uploaded on Drive) rather than sending the link to the video personally? Less time consuming and ppl with similar problems might be benefited and someone might be able to  solve the problem quickly?  :hatsoff:

Are the ESC properly calibrated upto the endpoints?


Title: Re: Help on quad copter
Post by: jeet8066 on April 30, 2015, 01:22:36 PM
yes all configuration are proper & all motors are starts same time.

I think you have mounted the props in the wrong direction  cw props on ccw turning motor(as KK Iyer Sir suggested).....put the throttle at 20-30% and by putting the hand over the prop(BEWARE: keep safe distance!!!!) if you feel the air hitting you hand you have mounted the props in the wrong place
Check in which direction the motors are spinning
This might help

Hello Jeet. I am assuming you have carried out all the steps involved in setting up the flight controller as referenced in the manual  here  (https://drive.google.com/file/d/0B4saiZvhGj-CejBRSU1HdHVfQWM/edit) as you are able to arm the quadcopter and spin the motors. This means the problem is probably due to motor direction or a battery issue. The propellers have been mounted correctly as per the photograph. Please verify whether each motor is actually spinning in the correct direction. And what is the battery voltage and individual cell voltages now?i

ok today i will check again.

@jeet8066,
Props and rotation ARE OK.
Don't fiddle with it.

Weight too much, or battery low.
Why is it flashing? Indicating low voltage?

To me it looks like low voltage or ESCs not caliberated, hence not recognising full throttle.
Before you do anything else, just post the battery voltage.


Title: Re: Help on quad copter
Post by: jeet8066 on April 30, 2015, 04:35:42 PM
Motor is armed hence light is flashing & weight is also very less. i this issue with battery.
