Guys, I have started to build my quadcopter.
Below are the parts bought so far:
KK 2.1.5 controller - eBay.in
Alien 500 frame - aliexpress.com
Flysky Radio receiver/transmitter - amazon.in
Please feel free to contact me if you have any parts to sell or suggestions.
I will update the post as I progress.
Thanks.
Edit: I bought this parts before I knew this group existed. Also anyone from Hyderabad know where I can buy the parts locally. I normally go to Gujarati gali in Koti to get some parts.
Good luck with your build :thumbsup:
Have you decided on motors ?
Thanks and No, not yet @sooraj. Any suggestions welcome.
Need motors that will eventually lift a small video camera:)
Go for the sunny sky 980 or 900kv. Very good and we'll priced motors and available locally at quadkopters.in or RCMUMBAI.

Thanks @ashimda, added it my list.
Is www.quadkopters.com (//http://) same as quadkopters.in?
These motors http://www.quadkopters.com/product/brushless-motors/sunnysky-angel-2212-980kv-brushless-motor/ (http://www.quadkopters.com/product/brushless-motors/sunnysky-angel-2212-980kv-brushless-motor/)
Instead of Sunnysky Angel motors, I would suggest to go for these, if you have the enough budget : http://www.quadkopters.com/product/brushless-motors/sunnysky-2216-11-900kv/ (http://www.quadkopters.com/product/brushless-motors/sunnysky-2216-11-900kv/) or this : http://www.quadkopters.com/product/brushless-motors/sunnysky-2212-980kv/ (http://www.quadkopters.com/product/brushless-motors/sunnysky-2212-980kv/)
I think Ashimda sir also mentioned these motors .
If you are low on budget, then you can opt this : http://www.quadkopters.com/product/brushless-motors/221213-1000kv-brushless-outrunner-motor-with-mount/ (http://www.quadkopters.com/product/brushless-motors/221213-1000kv-brushless-outrunner-motor-with-mount/) - this motors provide enough lift for an AUW up to 1.6Kg .
P.S : All these motors are way llot cheaper if you buy outside India !
@sooraj Thanks. OK I will go with 2212-980kv. Any idea what is different from 2216 and 2212?
Regarding buying outside, you mean online or physically?
Edit: I saw the difference from the site.
Just saw this in eBay, any comments on this
https://m.ebay.in/itm?itemId=301535934199
Sunnysky 2216 motor gives more lift and can handle up to 12 " props and is more efficient too , while with a 2212 you can only go with 10" or 11" props.
By, 'buying out side' - I meant online. (ebay, aliexpress , banggood ....)
Check this for eg : http://www.banggood.com/XXD-2212-750KV-Outrunner-Brushless-Motor-for-RC-Quadcopters-p-961973.html (http://www.banggood.com/XXD-2212-750KV-Outrunner-Brushless-Motor-for-RC-Quadcopters-p-961973.html)

Good combo - but 4 of such pairs will cost a heck , for that money, I can build a whole quad !!
Stick to sunnysky. :)

Thanks for the feedback, will go with sunnysky.
Planning to buy the below battery and charger
1. 3s 2200mAh 70C Wild Scorpion Nanotech lipo battery (http://rcmumbai.com/index.php/product/3s-2200mah-70c-wild-scorpion-nanotech-lipo-battery/ (http://rcmumbai.com/index.php/product/3s-2200mah-70c-wild-scorpion-nanotech-lipo-battery/))
2. Imax B6 (http://rcmumbai.com/index.php/product/imax-b6-copy/ (http://rcmumbai.com/index.php/product/imax-b6-copy/))
Appreciate your comments or any other combination of battery and charger recommended?
Are the selected charger and battery compatible?
There is no need for such a high C rating battery. 20-30C in enough. Spend 400/- bucks more and get the http://rcmumbai.com/index.php/product/3s-4200mah-30c-wild-scorpion-nanotech-lipo-battery/ (http://rcmumbai.com/index.php/product/3s-4200mah-30c-wild-scorpion-nanotech-lipo-battery/) longer flight times and enough punch for your setup.
@ashimda thank you sir for your feedback. I will go with your recommendation :thumbsup:
Here is the motors I am planning to buy from banggood
Honestly speaking, You Get What You Pay For. You are spending approx 4200/- on Motors and ESC's where as 4 good quality motors cost about 4000/- alone. Any good quality 750kv motor would cost 4x as much as the BangGood ones. But there's a reason for that. Well balanced with quality bearings and the option to go 4S are just a few.
If you haven't yet purchased them, I would have a rethink.

No Sir, I havent purchased them. I have put them in cart to get feedback from the veterans here. Definitely, I dont want low quality, at the same time it I dont want to spend a fortune on it. Any mid quality motors will do for now, as this is my first quad and more of a learning experience.
Any feedback on this 4in1 ESC ?
http://rcmumbai.com/index.php/product/multirotor-4in1-esc425a/ (http://rcmumbai.com/index.php/product/multirotor-4in1-esc425a/)
http://rcmumbai.com/index.php/product/multirotor-4in1-esc430a/ (http://rcmumbai.com/index.php/product/multirotor-4in1-esc430a/)
Updated parts going to buy based on valuable feedback :salute:
Not sure if I should go with 4in1 ESC or individual :headscratch:
currently using emax 2216 810kv motors.. good motors. very less vibrations , you can use props between 9'' to 12'' ( they are available in both thread cw and ccw for self locking props.)
http://www.rcdhamaka.com/index.php?main_page=product_info&cPath=100_93&products_id=1470 (http://www.rcdhamaka.com/index.php?main_page=product_info&cPath=100_93&products_id=1470)
(these motors provide enough thrust to lift my quad at almost 60-70% throttle weight around 1.3kg with 3s battery and 9443 self locking props)
i also try my hands on 2212 motors but 2216 gives better performance as compared to 2212 ( also these can handle more weight than 2212 for future upgrade)
goodluck :thumbsup:
regards
go for these ESC http://www.quadkopters.com/product/esc-ubec/simonk-esc-20a/ (http://www.quadkopters.com/product/esc-ubec/simonk-esc-20a/) (4 individual ESC)
instead of buying 4 in 1 ESC..

Thanks @gunnu.
Was looking for 30A as I am not sure about the motor capacity. How about this http://www.quadkopters.com/product/esc-ubec/simonk-esc-30a/ (http://www.quadkopters.com/product/esc-ubec/simonk-esc-30a/) ?
hmmm i am using this ESC but currently out of stock.. emax simonk 30A esc are also good.. check this link
http://rcmumbai.com/index.php/product/simonk-30a-esc/ (http://rcmumbai.com/index.php/product/simonk-30a-esc/)
(for multirotor always use simonk flashed ESC)

OK, noted and changed to separate ESC.
Much better choice of electronics :thumbsup:
I fly a Tbs Discovery (which is similar to your frame) with the SS-980kv motors on 3s & 4s. AUW with 4200 3s 20c, 9" props, gimbal/SJ4000 cam, 600mw vtx is 1562g and I get 8min comfortable flying time.
with my previous motors ( turnigy multistar 2212 920kv) i get almost 14 mint flight time (3s 4400mAh battery and 1045 props)
today ill test with (4s 5000mAh battery and 1045 props and emax 2216 motors)
Maybe 9" on 4s would be a safer bet. You could try 10" but keep an eye on motor temps.
Is this charger http://rcmumbai.com/index.php/product/imax-b6-copy/ (http://rcmumbai.com/index.php/product/imax-b6-copy/) good for charging this battery
http://rcmumbai.com/index.php/product/3s-4200mah-30c-wild-scorpion-nanotech-lipo-battery/ (http://rcmumbai.com/index.php/product/3s-4200mah-30c-wild-scorpion-nanotech-lipo-battery/) ?
as per emax prop chart (thrust chart) for 2216 810kv they recommend max. prop size is 11'' and min. 10'' they didn't mention 9'' anywhere with 810 kv motor.. i test these props on my behalf..
yup you can charge any lipo between 1S-6S with charger..

Sorry I thought you were talking about the multistar 2212 920kv.
ok...
How does one figure out the customs when buying from outside sites ?. Does it get shown when placing the order or we will only know when shipping company delivers the item ?. Any insights as to what is the usual customs duty to be paid on motors, esc and other quad/plane parts?
@paithal32 do a little search and you will find everything...

Try this thread I found here
http://www.rcindia.org/index.php?topic=11052.0
I did the following calculation, appreciate if veterans can verify:
For SunnySky 2212 980kv motor
- with 1047 prop, for 3S lipo, current is 13.2 A
- ESC should be atleast 13.2 * 1.3= 17A
So 20A ESC should be fine
- lipo should discharge continuously 17A or more
Then a 1000mAh with 20C will discharge (1000*20/1000) 20 A
Edit: considering 4 motors (as corrected by Sooraj)
13 * 4 = 52 A then lipo should be at least 2200mAH * 25C = 55A
Any idea how to calculate the time at 100% motor usage?
Here is approximate calculation with constant current draw of 13A from 2200mAh LiPo will get ( 2200mAh /1000) / 13A = 0.1692 x 60 = 10.15 minutes flying time.
There is a little error in your calculation for lipo - you have considered LiPo for only a single motor ??? !!
Well you need atleast 2200mAh 25C or higher for a few minutes of flight time .

Good catch @Suraj and thanks.
So does that mean (20*4) 80A required? then it would require a bigger lipo than 2200mAH 25c ?
Or if we go with (13*4) 52A, then 2200mAH 25C (55A) should do.
Isn't the 13amps you stated for 100% throttle? Since we rarely fly our quads with full throttle, I'm guessing 20-25 amps for hover
(4 motors). If I'm right 2000mah 20c lipo equals 40amps which should manage or 5000mah 10c = 50amps will do as well.
Then again I could be wrong.
A wild guess would yeild you around 6-9mins, better setup can get you around 13mins with 2200mah 3s lipo.

You are right Sir.
Here is approximate calculation with constant current draw of 13A from 2200mAh LiPo will get ( 2200mAh /1000) / 13A = 0.1692 x 60 = 10.15 minutes flying time.
[Admin Note] Unnecessary quote of just prior post removed. Please use "Reply" (or the "Quick Reply" box at the bottom) instead of using "Quote" while responding to the last post in a thread.
Again my friend you are considering the current draw by only one motor. !!!
The 13A is the max. current draw by your motor (At full throttle.) so the highest current draw of your quad can only be 13 x 4 = 52 Amps - but the fact is you don't have to get a LiPo that can yield these much current at all as we don't fly at full throttle - still getting a LiPo that exceeds the max. possible current draw is good because you won't wear out that LiPo quickly, even if you fly at full throttle .
For your setup , a 2200mAh 25C LiPo is enough, it also has a safety margin of 3Amps - with this battery, even if you continuously fly at full throttle :giggle: you can still expect a whooping 1.15min flight time !!!! (considering current draw at full throttle = 50Amps !! ))
Edited the post due to wrong calculated figures :banghead:

Right @Sooraj Sir, but how did you get 49A? 13*4 = 52?
Ooh ! man, so people are right, i am bad at mathematics sometimes - messed it up while calculating in mind (hah lost a 3 somewhere!!) :banghead:
Thanks for finding it, and bad of me that, i didn't reread my post .
Now what a mess, all that post is with wrong figures, can I have the privilege to edit it ? :giggle:

I got my flysky FS-CT6B today :) and looking for any links/pointers to set it up and configure it for quadcopter.
Thanks
And got my kk 2.1.5 (:|~
The KK 2.1.5 came with 1.6 firmware version, do I need to upgrade it? Or good to go?
You can use it as it is but you could flash a custom FW like the RC911.

Anyone tried flashing the KK firmware using arduino ?
I would recommend the latest Steveis firmware. I have tried flashing with Arduino, it work pretty well. USBasp is simpler though

I tried that as well, but no luck.:(
Double check the ICSP connections, Check the reset pin on KK board's ICSP connector is connected to Arduino Reset .
With which program you are trying to upload the HEX file ? Command line interface ?
I went by this docs http://blog.oscarliang.net/flash-kk20-16-firmware-upgrade-arduino/ (http://blog.oscarliang.net/flash-kk20-16-firmware-upgrade-arduino/)
KK RST is connected to PIN 10 Arduino.
Just a note, the power to KK is supplied by 9v - stepped down by regulator KA7805 to 5v, not sure if this will cause any issue.
If you are powering KK2 with another source, you should make sure the arduino and KK2 have a common ground . use a jumper to short arduino and KK2 Grounds.
Just tried with common ground, no luck still. Thanks @sooraj for helping me out.

Is COM3 the right port? The port that your Arduino is on? You are flashing from the command line right? Have you uploaded the Arduino as ISP sketch to the Arduino? Please post the exact command you are using.
Oh, and try changing Arduino to avrisp as the programmer type.
COM3 is the port arduino is connected.
The command I used quoted on your post (above).
Yes, uploaded the sketch as ISP also.
Now tried with the 10uf capacitor between RST and GND.
Didnt try changing Arduino to avrisp as the programmer type yet, will try.
OK, tried as avrisp and new error :help:

its funny because I would be so ignorant (or whatever) to ask for help
disconnect your kk board from power source if you are powering it separately while flashing (you are using ardunio as isp correct?)..

Man - board is not dead, and it will never be, until you supply reverse polarity, or set wrong fuses.
Don't worry about that.

What you mean reverse polarity?
OK guys, got it flashed.
It seems like the issue was the serial driver. It started working after reinstalling the com driver.
Thanks @phanivyas, @SK1701, @sooraj.palakkad for spending time to debug with me. :salute:

Quick question, what is the connector to connect xt60(female from lipo) to lipo charger female banana plug?
OK, got xt60 male to dean female, from Satya, quadkopters
That is right connector that you have selected
@Satyagupta thanks for expediting the orders quickly.
I request for a clarification on kk2.1.5 ESC connection!
Should the power and ground pin be removed from ESC bec for M2 to M4? In other words, only M1 should have 3 pin connected, rest only signal pins?
As far as I know for KK2.0 no need to remove any wires from your ESCs. Connect them as it is with signal on the left pin and Gnd. on the right pin. But for Ail, Ele, Thr & Rud pins you can connect the 3 wires to Ail and remove the Gnd & Vcc from the other 3 pins. I mean you can only connect the signal wire to Ele, Thr & Rud pins. I guess this is same for KK2.1.5
Thanks @meet2ami, that's what I read too regarding 2.0 but not finding any documentation on 2.1.5
@jsquadman, you can follow documentation for KK2.0 on KK2.1 too :)
OK thanks @sooraj
The receiver and ESCs connections for 2.0 and 2.1.5 are same. Here's one link that may help you:

On my 3S lipo, I am seeing 11.69v (measured in lipo charger and volt meter).
Is there something to worry about? Or should I discharge it?
That is nothing to worry about. A fully charged 3S LiPo should reach 12.6V (4.2V per cell) and at nominal voltage 11.1V. You can discharge it lower than that but 11.1V is a good threshold for maximum battery life. Just check your individual cell voltages, they should be with 0.1V of each other.
Thanks @SK1701 I thought at full charge it should be 3.7*3 = 11.1v
If you have not already purchased one, get a lipo alarm and set the alarm to 3.6-3.7V.(3.7 X 3 =11.1V). When you hear the alarm, land the quad and your quad and battery are safe.
@ashimda not bought voltage alarm yet, any recommended from lhs?
Got all the parts but as I was soldering, the iron blew up on me.
Now waiting for another soldering iron to continue the build.
You can use any one of these:

I am using them, they are better as they display the voltage as well as triggers alarm when voltage below the thresold you set.
Thanks @meet2ami. Looks like eBay one looks better (from the pics)
I use the same lipo alarm. It does the job.
@jsquadman: Both are same. The one in Hobbysea is with an extra plastic case. Thats it.
Thanks @meet2ami for clarification.
Was able to fly the build, but it is always tilting to one side, need some tuning -- check it out
Maiden flight: https://youtu.be/zXbzgxsazKs
Second flight: http://youtu.be/dDh4x7GFlcM
Attached some pics of almost complete quad.
Here is one flight video

Looks like I am trigger happy on throttle, and the quad really takes off.
What parameters should be changed in kk to reduce throttle sensitivity?
Firstly when you go to fly, pick a proper wide open area to practice. A place where there are no people and nothing over head like trees or power lines.
Secondly you need expo on your throttle to dumb it down so you can control the altitude.
Congrats on the maiden and keep practicing.
@ashimda, thanks for advise. I am trying my best to avoid people and other objects but in my locality its almost impossible.
I am looking for an open area near Kondapur, Hyderabad. If anyone know any open space near by, please ping me.
I am getting an error in sensor test when I tilt the copter.
Am I supposed to tilt it while testing?
