Hi friends

i am building a quadcopter.
specs are as following

frame :- tarot iron man 650
motors:-  turnigy 4206-530kv
esc :-    30 amp esc simonk
Flight controller :- multiwii mini aeorc
rx tx:- turnigy 9xr with flysky rx tx module
battery :- turnigy 2200mah 3s1p
blades :-    12x4.5 abs plastic

problem is i does not lift from ground.
i checked the motors direction.
the are ok, but still in vain.
any help is most welcome.

What exactly do you mean by not taking off? Not enough thrust or that it's very unstable on lift off?

hi
Are you using Same props for 4 motors?? You should use 2CW props and 2 CCW Props

please check your props....

Not enough thrust
Ans peops are cw and ccw

guys help will be highliy appriciated?

i really need it to fly.

Could you post a video of you trying to lift it, people might be able to help you better.

use big props as i told u, the problem will be fixed, or for even more power go with 12-13" props and 4S battery at least. even the capacity u are using isnt enough, get a 4Ah atleast

friends my battery got puffed and i had to destroy it.
now i am one battery short for transmitter or i say for copter.
i'll be back when i got a new battery. any suggestions which battery shall i buy?/

A single motor you are using on average draws 20-25amps max with 3s lipo and 12" props(approx figures). So you should get a battery which can discharge 80amps (minimum)at a given time. I hope you know how to calculate current discharge rate of a battery (mah * C/1000)

i.e if going for a 3s 2200 mah lipo then it should be 40C+,
or 3s 3000 mah lipo should have 30C+
or 3s 4000 mah lipo should have 20C+

Going for higher capacity will increase weight of your multirotor considerably, which would make it inefficient, so my opinion would be sticking to 4000mah , you can also use a 4s battery but then your current draw may increase to 100amp so select battery accordingly.

Now, you never mentioned discharge rate of previous lipo. The primary reason for a puffed battery is over draw of current while in use or short circuit, and I believe in your case it was over draw.

Not sure what you meant there but dont use the low discharge transmitter battery for you copter, its not adequate.

And please read more about the subject you are dealing with, because a little knowledge is a dangerous thing! You just lost your battery because of your lack of awareness which could have been dangerous too.

Thankyou very much for response
Yes you got it right
Please recommend battery for tx controller and i'll try to understand every bit of it

For transmitter you can use any low discharge batteries such as
http://www.hobbyking.com/hobbyking/store/__31315__turnigy_9xr_safety_protected_11_1v_3s_2200mah_1_5c_transmitter_pack.html

You can also use any 2/3s battery which fits inside the battery slot of any discharge rates, altho low discharge batteries are recommended. I use a 1300mah & 500mah 2s lipo 20C for my Flysky 9ch Tx.

The battery i use for transmitter and quad is same turnigy 2200 mah 30c 3s1p.

hi friends

my quad still doesn't lifts off.
i changed my battery to 4000 mah 4s1p 20c
but still it doesn't lifts off.
in fact there is something new. fourth motor does not rotate on 20 % throttle i have to raise it to
more than 50%.
friends please help me.
i am using aeorc mini as flight controller, if any of you have got kk 2.0 or kk2.1 (used)
please let me know.

Are you using same Battery for transmitter and quad ?? 
2200 mah 30c 3s1p ??

i think you need to use lower C rating battery for your Transmitter.

Please provide a Video of your Quad..

please check Rotation of your prop maybe its wrong.

Please calibrate all ESCs Before start any Testing.

I hope it can Help to you...

Post your video so we can check what is the problem...

Thanks...

th ebattery is 20 c not 30 c sorry for mistake.

and i am using 4000 mah 20c fot the quad.

20c for transmitter ??

this is not good...maybe it can be damage your transmitter..

you must need to use Lower C rating battery.

friends i've dropped the quadcopter ides.
parts are on sale.
please check sale section if intrested.
