hey brother my team is going to make a quadrotor...
and i hav all comments here...
can u plz tell me the making cost of quadrotor..
i ahv to lift 1.5 kg....
and i want ceiling abt 100 meter..
plz help me... my id is avdhruva@gmail.com

I hope you have spend some time on the forum on the quadrotor stuff. This seems to be a commonly asked question, with no ONE particular answer.  It is somewhat similar to saying I want to buy a bike, which hardly describes the task in any detail... there are so many choices and decisions to be made along the way.

Please go through the various quad related threads, and then ask specific questions.  There is only intermediate level experience in quads here... everyone seems to be in various stages of learning :)

thanks anwar......
u right...n nw i hav read much here.....
so now i m going to make my quadrotor...with this specification
weight 1.5 kg...frame made from balsa wood...
18A-ESC , 2210N brushless motor GWS9050@3s
battery is 5000mah 15C
so plz suggest me abt the props and is necessary to add gyro and accelerometer in my quad...
bcoz i m nt making a autonomous quad...and my budget is abt 20000...
and from where i can buy these parts in india...

hi my team is going to it make a quadrotor can u tell me from where can i get 2210N brushless motors for in india
plz help......

Contact me I have all the spares required to build one...

avdhruva since you said your making quadrotor for first time try not using gyros instead use servos to tilt your motors slightly.one servo for normal rotating motors and one for counter rotating.as you said you are beginner gyros are not so easy to understand and they are way too costly.

We have a Quad with board that can be assembled and flown :

Sai

mate gyro gives stability.idea of servo to tilt the motor is good but without gyro it will make job difficult infact impossible to control quad.

i am planning to build a quad-rotor helicopter. Can u please suggest some sites or books that can help me do so.......

please use search option first and contact the persons who posted the related threads..
Welcome to rcindia..

hi anwar.
 :)
i need to know is their any appropriate dimension ratios for a quadrotor. "diagonal to sides" for a lift up i am making a quad X


it is 82 cm from prop(center) to prop(center) diagonally  and 58.2 sideways ..... my quad wiegh about 3 kg  8-)


so is this okey with the physics. ???

hi, do u have a price list for the parts tp make a quadcopter ? plz reply thanx.

I want to know what should be the minimum budget to make a quadcopter just with the motive that it should stay in air at height near 5-10 metres for 2-3 minutes?
Also describe the body material
Can thermocol be used for making the body parts?

hi welcome to RcIndia!

why dont you start here? >> http://www.rcindia.org/rc-india-forum/the-rc-india-gems/

the questions you ask have been answered dozens of times... just use the search bar at the top right corner of the screen to search... :)

thanks

hello guy, i am new in here.....
i want to built a quadcopter (i don't have any past experience). my whole quadcopter weight should be around 1.5kgs.
what esc and motors do you guys recommend?

Please use search feature. This have been asked and answered by many times

I think you've all the parts ...you just need motors and esc.....then also im give all the parts required for quad

The motors and esc's listed are the best in terms of price so if you want good performance without being costly these are for you.....

And for quad you need motors having low KV prefer from 800-1200kv motors as they will provide more thrust....


.im also posting links to hobbyking so you can easily buy....Mostly i will focus on best but no heavy on cost so here it is....

Frame-I would say you should make your own frame as its easy....but if you want readymade here are some

Hobbyking quad frame 680mm(9.95$)-http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=20947&aff=1139072

Motors-Turnigy 2836/8  1100kv  (12.50$)-http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=18969&aff=1139072

Esc-hobbyking 30a esc 3a ubec(9.99$)-http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=15205&aff=1139072

Lipo batteries-turnigy 3s 2200mah  20-30c. (7.89$) -http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=8932&aff=1139072

Flight controller- as you are beginner i would recommend kk multicopter v2.0 board as it is very easy to use it has preset for quad select that and you are ready to fly....here's the link

Kk multicopter v2.0  (29.99$)-http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=24723&aff=1139072

Radio set (Tx & Rx)- i would recommend to buy this from indian shops as it will increase the shipping weight a lot....so heres the link for radio se 6ch with Tx and Rx...

Radio set (Tx & Rx) (Rs-3280)-http://thehobbyshop.in/index.php?main_page=product_info&cPath=74_9&products_id=21

Propellers 10x4.5(2lh, 2rh). (2.65$)-http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=25824&aff=1139072

Power distribution board(3.89$)-http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=23140&aff=1139072


Total weight will be....1122gms

Your budget is 20000, then also your using low end motors and esc's.....make use of that money.....at that much money you could get high performance quad.....

I am trying to make a quadcopter :banghead:(i have some programming knowledge). I am seeing that many quads are made from brushless motors. I am trying to make one using a brushed 5oooorpm motor. I am following this link:
http://www.rcgroups.com/forums/showthread.php?t=1710948  
 (above link shows a quad made out of 18$........only thing i dont understand is the board he use? is it arduino compitable? programable? dose it have IMU or 6 DOF sensors?? )


That guy uses a board of unknown specifications (if you know just inform me).

so I am going to use an Arduino Uno microcontroller to make my own flight controller with 6 dof IMU.
Here is my parts list:
  
 1. arduino uno(micro controller)
 2. four motors(just look at rcgroup link.since i cannot post more than 2).
 3. propellers
 4.a 9v 1200mAhr lipo
 5. trans receivers

I don't have a radio controller. Is it possible to build one
using two of these?
http://www.fasttech.com/products/1005/10002877/1215201-nrf24l01-enhanced-24ghz-wireless-transceiver-modul

Using arduino on both ends (quad and DIY joystick).
For ESC what should i do? can i use uln2003 or mje13005 transistor(connect motor across EC and pwm at B)?is there any DIY ESC available to make

for motor which one is good for flying  from this list

http://www.fasttech.com/products/1014/10003892/1278006-3v-dc-micro-motor-ff-k30wd-8z107

I am trying to finish it within 30 or 35$.

give me some link about design and electronics
First of all is it possible using the above parts list? ???

Hi Viki,
Welcome to the forum, :thumbsup:

1.Brushless motors are preferred for aeromodelling because of their ability to produce lot of thrust and good efficiency throught their lifespan.

2.Me either have no idea about quads,

3.anyways it isnt recommended to go for complete scratch  building of everything, atleast the Tx and RX part. 

4.the board used is a controller board that takes care of controlling all the motors to spin at constant rpm to produce equal thrust to balance the multicopter.

5.Maybe you can try the below links
http://www.quadkopters.com/product/998-v2-2-4g-4ch-mini-quadcopter-with-vga-camera/
http://www.quadkopters.com/product/qk525-arf-rtf-quadcopter-kit/

6.Escs arent hard to scratchbuild but building them is a tedious job, and might be heavier and bigger than readymade ones. might not be power efficient always.

7.the given link has a readymade kit which might come under your budget.

Happy flying.
AK.

There are some major things you have not considered.

First of all, the RCG person just used a commercial controller, which has the flight controller, 3 axis gyro, 4 ESCs and a receiver in a single unit, so all he needs are motors, props and a transmitter.  Basically, it is the board that powers these ultra cheap (and really small) quads. Nothing outstanding about what he has done, and very little DIY it seems.

This is the commercial quad from which he took the controller : http://www.banggood.com/buy/WL-929-quad.html

This is the controller all-in-one unit : http://www.banggood.com/Wholesale-WLtoys-V939-Beetle-4-Axis-Quadcopter-Spare-Parts-PCB-Receiving-Board-V939-05-p-49468.html

Your parts list is missing some key items, like the radio TX RX, 3 axis gyro/6DOF IMU, ESCs etc. Not to discourage you from trying, but hand crafting even some of these (tx/rx or ESCs) can itself become quite an effort.

Overall, you need to spend a whole lot more time on this forum and elsewhere, then decide how much DIY you want to do. Currently, you seem to have bitten more than what you can chew.

There are some errors in "v2 eagle"s responses to your questions also. Specifically, the job of controller is NOT to maintain constant RPM, but offset unintended changes in orientation of the craft by constantly adjusting the speeds of different motors to keep the craft level, based on a feedback loop from the 3 axis gyros (or you can think about the same in terms of an "inertial measurement unit"/IMU with 6 "degrees of freedom"/DOF).

Sorry Anwar,
 I tried my best to explain Viki about how the controller board works.  :banghead:

Thanks
AK.

thanks for the reply

what about the links to the motor i posted?

if i buy above said flight controller or any other controller should i have to program it or it comes pre programmed?

you can get this quadcopter set http://www.quadkopters.com/product/diy-v939-quadcopter-kit/ (http://www.quadkopters.com/product/diy-v939-quadcopter-kit/)
this one comes with a flight controller board also so enjoy your quad you would just require a tx,rx set

hello bro im also from jaipur ....and i can help you.. :)

thnx :salute:

How to choose Motor and Propeller for Quadcopter.. high thrust,high carry weight, 20-30amp ESC , low cost  :Rs:?


pls help  :headscratch:

A low kv motor is good for a quad, like about 1000kv or below, prop size in the range of 9"-11"inch which depends upon your battery setup and costs  above 10k for a good setup if you already have a radio or else you have to spend more for a radio.
Take some time reading threads and googling will help you.

decide how much weight u want to carry, what u want it to do, your exact budget,etc

Hi Avadhut, welcome to the Forum  :)
Refer to the following link:
http://www.rcindia.org/multirotors/choosing-motors-and-the-propellers-for-quadcopter/ (http://www.rcindia.org/multirotors/choosing-motors-and-the-propellers-for-quadcopter/)

yes. i want to carry 1-2kg weight ... camera and other dropping

pls help !

You can refer to this thread for getting an idea about what all you would need:
http://www.rcindia.org/multirotors/choosing-motors-and-the-propellers-for-quadcopter/ (http://www.rcindia.org/multirotors/choosing-motors-and-the-propellers-for-quadcopter/)

Read it completely. After getting a brief idea, then you can ask any specific doubts you have over here.

Thanks !  :hatsoff: :salute: :thumbsup:

Hi there!

I am also doing some research as I want to build/purchase my own quad.  You can check this link out:-

http://oddcopter.com/2012/12/12/easy-diy-quadcopter-build-part-1-the-parts-list/ (http://oddcopter.com/2012/12/12/easy-diy-quadcopter-build-part-1-the-parts-list/)

Parts are good. You can also use the following ESCs:
http://hobbyking.com/hobbyking/store/__9483__Mystery_30A_BEC_Brushless_Speed_Controller_Blue_Series_.html (http://hobbyking.com/hobbyking/store/__9483__Mystery_30A_BEC_Brushless_Speed_Controller_Blue_Series_.html)
http://hobbyking.com/hobbyking/store/__13429__HobbyKing_30A_BlueSeries_Brushless_Speed_Controller.html (http://hobbyking.com/hobbyking/store/__13429__HobbyKing_30A_BlueSeries_Brushless_Speed_Controller.html)

You can also save some money if you are willing to scratch build the frame. It isn't very hard. All you need is Plywood and 1/2" square wooden booms.

The radio mentioned in that parts list is a very cheap option. I would suggest you to put in a little more money and buy atleast a 6 channel programmable radio. It will save you a lot of money later, as you won't have to buy another radio when you need a programmable one.

A word of advice, preferably do not order a radio from an international site as it gets stuck at customs. It would be better to order a radio from a local hobby shop.
Take a look at this:

Thanks...will look into it.

Hello to all .. I'm New to qquadcopters... I've got my tx from flysky .. Pls tell me from where should I buy the frame and other components since I request u all to give me suggestions about hobbyking .. and what will be the rates when compared with the ones I buy in India .. Pls help ...

@irshtin,
Welcome to RC India.
Please do a little searching on this forum.
Adequate info is available.
You can start by looking at www.quadkopters.com (http://)
Then search for Mega list of RC outlets (on the home page of RCI)
There are now many Indian online stores with good reputation.
Best wishes.

i think sticking with quadkopters is a good idea for newbie.

Thanks for your suggestions .. when I compared the rates from hobbyking,many items r heavily prized here when compared to hobbyking ..so I've made a decision to buy from hobbyking ... help me with it pls ...

The items might be a little expensive here but I suggest you buy from India . If you take the shipping charges , time and customs in consideration you wont be buying from Hobbyking . If you buy from your local hobby shop you can return the damaged or defective items .

Bought 10meter 6mm rubber tube from Hobbyking for USD 3.69, say Rs200.
Ended up paying Rs 850, due to shipping cost...

One lives and learns.

As an experiment, compare the landed cost of say a 'Sunbird' kit for Hobbyking, against the price from RCB/RCD Bangalore.

you can also check out rcmumbai.com

use aluminium or plastic for frame.
