Reather than that buy cheapest one at banggood.com and select expedite shipping and before paying inform them in comments to declare only 20% of the total value
No customs hassels then
U get a rtf quad fr cheap without paying customs
And shipping at banggood is cheaper the hk

why? wont my rcb6i work?


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: tej on January 12, 2014, 04:54:51 PM
don't get the hk 19$ quad, it has some board problems and the spare parts are not easliy available. Also you pay 25$ for shipping so it makes around 45$ quad. If you want to get a quad from hk, buy a hk qbot(v929) quad or ufo y-4. Hobbyking accepts Indian visa debit cards, no need for paypal!

if you have a paypal account Get a hubsan x4 v2 or v252 cheapest from banggood which has led light for night flying and can get lots of cheap spare parts.

If you don't have a paypal account to get from banggood, buy a clone of v929 rtf from rcbazzar.com!

why? wont my rcb6i work?

it doesn't have a necessary protocol for wl quads!

Post by: roby on January 12, 2014, 05:03:15 PM
if i'll build my own quad, wont it be a lots more cheaper?
hey i've not made a quad so far so have no idea whether my r.c. will work with it.
will i have to program my rcb6i?what difference will different control boards make?
all boards have gyros and necessary components i guess.


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: tej on January 12, 2014, 05:12:43 PM
yes! but the protocols used in the boards are different.

What size are you talking about? If you are looking for 450/330 size, then you can build and use your radio, as the receiver will be of rcb6i

but a micro branded one can not be bind with your mentioned tx. As the receiver is inbuild which follows a different protocol than your tx! hope you understand!


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: roby on January 12, 2014, 05:15:21 PM
hey pls explain me whats 450/330.. i might sound really dumb, sry ..i nvr built a quad..
pls use the most basic terms u can


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: tej on January 12, 2014, 05:28:19 PM
it's the size in mm 600/450/330. You want to practice indoors or outdoors?

http://www.hobbyking.com/hobbyking/store/__502__501__Multi_Rotors_Parts-Frame_Kits.html (http://www.hobbyking.com/hobbyking/store/__502__501__Multi_Rotors_Parts-Frame_Kits.html)

If you are complete beginner looking for quad then I would suggest get a micro as you will crash a lot in beginning and will need spares to repair. Mostly you will break with micros are the props or motors which you can buy for very cheap price but crashing a 450 would be a nightmare for a beginner as it would cost you a lots of dollars to repair plus micro quads are good trainer for orientation which will help you manage a bigger quad easily.

When you are good in flying micro go for bigger quad. Crashing and repairing micros will help you understand more about how quad works when you build your own 450 quad!

Hope this helps!


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: roby on January 12, 2014, 05:39:56 PM
outdoors for sure..and hey, how much will it cost to build one? cant i just get the motors esc and a control board and make one?


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: tej on January 12, 2014, 05:52:34 PM
you can make your own frame AND save YOUR 10$ for other parts. The motors/ esc/ board/ lipo's /charger/programming card/ cables/ amd other small necessary stulls will cost you around 120$ plus shipping and customs duty if caught! Around Rs- 7-8k from hk without customs

but ofcourse you ca get it for more cheap with cheaper parts but it won't give you good power for aerobatics! Just to fly!

eg- you can get a 2212 motor instead of 2826 but it will be very hot if you fly too fast and eventually give up. That would cause disaster in the mid air if that happens!

@ROBY: Do you have a good soldering skills?


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: roby on January 12, 2014, 06:13:15 PM
nope, but lab assistants at our college do it pretty well.. so heyy, thats not an issue


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: tej on January 12, 2014, 06:32:17 PM
Have you used a sim for practice?

if you are confident then get a bigger quad. But I would still suggest a v929 which you can fly outdoors and practice indoors as well for a beginner. It's up to you! all the best!


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: roby on January 12, 2014, 06:35:49 PM
i ordered a sim, hey the thing i wanna know is totally different..
there are some cheap avionic motors and esc at rcbazaar and cheap controller board at quadcopters. i wanna know a suitable combination which will be best for a quad.
plus what extra things do i necessarily need?


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: tej on January 12, 2014, 06:49:05 PM
main board is the heart of quad so get a good board. I would suggest kk2.0/2.1.

Don't get any motor. First decide what size you want to build. Motor size depends on that. If 330 then you can use small cheap 2212 motors than 450 which use 2622

check this 2 different video series! follow it and you will understand all things you need to get started!

thanks a lot taj that was a great help.. by 2212 u mean kv rating or the model no?
i dnt wanna spend much, 330 mm is cool :D


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: roby on January 12, 2014, 06:59:39 PM
1 more thing buddy.. i have a 1250mah 3s lipo...pls let me know if there is a suitable configuration of esc,motor and prop for this particular lipo


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: tej on January 12, 2014, 08:10:01 PM
you can use various motor size and esc with the mentioned lipo! 2826- 2812 MOTOR with 15-20 amp esc would be perfect depending on the size! prop depends on the motor you using!

but remember the motor max current drawn should be lesser than the esc contact current provided. at least 2-5a gap... eg- motor 10A, esc 15a
also make sure the 4 motor thrust is greater than the total weight of quad.
use 3 esc with disabled bec and one enabled bec or else you will fry your receiver! Bec use for receiver powering should be 5.5v not more!

Try this motors and ecs! cheapest as it gets!

Make the paper quad search on flitetest and youtube about paper quad and build it order the elecs frome hk. If you dont want to order from hk you can order from rcb or rcd.

http://www.quadkopters.com/product/cf250-quadcopter-arf-kit/ (http://www.quadkopters.com/product/cf250-quadcopter-arf-kit/)

can u review this quad? is it good?


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: tej on January 12, 2014, 09:39:17 PM
looks like a good deal but its 230 size! Much smaller than 330 and 450! I doubt it can be use for fpv in future but you can use the electronics in f330 quad frame which you can buy at hk for 8$ for fpv

 If you don't want for fpv then it's a good deal for small quad! Get it!


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: roby on January 12, 2014, 09:41:57 PM
thanks.. and there's no programmer available with this quad..right?
so will i be able to fly it with my rcb6i?

sry if the question seems inappropriate, i dnt have much knowledge.


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: tej on January 12, 2014, 10:56:44 PM
of course you can, its plug n play. you have your receiver right? plug the receiver with the board

but there are some setting to need to program before start. This board can be used in x/y/+ configurations so if its programmed then good. Discuss this with the vendor before buying!


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: roby on January 12, 2014, 11:19:56 PM
i will. and it should be set in x config i guess.. right?
how do we make connections? like pin 3 is of throttle, so will it lift the quad?
and elevators?


Title: Re: want DIY V939 Quadcopter Kit from quadcoptors.com
Post by: tej on January 12, 2014, 11:28:27 PM
If it's programmable then you will get a usb to connect it with you pc and you can download software to set it! ASK your vendor as it says lite version, it might be preprogrammed only for x mode!

Post by: rcrcnitesh on January 13, 2014, 01:46:50 PM
If you want to build a quad and not do this one it is great I made the frame it is very strong just waiting for the elecs. If you want to build even a larger one than this use A3 Size paper and if you want it to be even stronger put some hardwood dowels or cf rods or tubes of the correct size measure the thickness of the gap and get a dowel of that size.
You will face trouble rolling the Sheet for that you can use that dowel or use some barbeque sticks for rolling.
