hi everyone,  :)
Been getting into quads lately. This was my first semi plan built quad. I had initially bought sets of motor for my 450 flamewheel quad, i couldnt mount them in that frame. so being left with only motors i made a scratch built H quad(first pic below) so that i could learn to fly better, but since its arm broke and there were a few flaws in it. I came up with this quad for my learning platform..  :)

Im still learning how to fly and this thing still has to be fine tuned.

I would like to thank Veloci for his help in flashing the kk2.
sources of items used - rcdhamaka, rcbazaar, Adiboy, quadkopters, and hobbysea, i will buy items from them again. Great support.

frame specs-  bought items from sp road, blr.
aluminium square tube - 16mm x 16mm x 190mm (1mm thickness) - 6 pieces. - 4 arms and 2 frame braces.
glass fiber sheet - 2mm .
screws and nuts.
sponge landing gears.
lots of zip ties
double side tape
used dremel and drill to get the shapes.

electonics-
frsky v8ll rx
emax 18 amp escs
1200 kv motors
8 x 4.5 props
KK2.0 FC. v 1.5 ,
3s lipo. it carries both 2200mah and 3300mah lipos
AUW- Will have to find out.  ;D

Do give in all valuable inputs and suggestions.  thank you

pics added.

This is so cool Pravesh! Pls maiden it soon!
Cheers!

EDIT - Is your Quad balanced properly? Can the bigger lipo counter the weight of the smaller one?

hi veloci and rahul , thank you. you guys' build thread inspired me to make one.
maiden done already but no videos or pics, but will click and upload some soon. quad is balanced i think because the lighter weight is more outward while the heavier is closer from centre and there are gonna be 2 cams in front. :) need to cross check though.

pic of layout added with 2200mah 3s.



veloci

Okay pravesh. But why are you using a low voltage buzzer when this feature is already present in the KK2?

Check this...


You can use a 'RMC' connector(local name for balance plug) instead of the JST as shown...
Cheers!

Nice build Pravesh. Just wonder what's the use of plastic spoon!

veloci

Dharmik bhai, that spoon has been strapped on for orientation i guess. ;-)

@veloci- when i got the kk2 i dint get a piezo buzzer with it , so i thot best is to use the other buzzer.
@dharmik, thank you. your build gave me a lot of ideas. spoon for orientation (thank u veloci). but it will soon be replaced by vtx if i learn to fly it better, ;).


edit- video link added. just flew it for the video sometime back.

veloci

Nice flying Pravesh!  {:)}
Next time, try hovering it in one place to test if its balanced....
Well done!  ;)
P.S - Get a buzzer from S.P road (Rs.5) and solder it to your KK2. 2 minute job.
Airplanes may kill you, but they ain't likely to hurt you.

Thank you Veloci. :)
will do hover to check balance today. getting the buzzer when i go to sp road again, i dint know it was available there.

veloci

Check OM ELECTRONICS, VISHAL ELECTRONICS or NSK.

Hi veloci,

I have brought ready to fly quad copter from RCBAZAAR, i am able to run all the motors however the autoleveling function is not working fine, can you please help me out to reactify this problem. If you dont mind kindly share me your conact number my number is 9740699448

pravesh736

hi again everyone,
I have got some updates/changes on my quad, like slightly redone frame to make it fly better, hybrid motors of emax and odin.  :P ..
5g8 FPV setup with cloverleafs and spw, cheap excellence OSD, f20a escs flashed simonk (never never ever going back to stock escs ever on any multi), black paint job... lol  ;). running kk2 v1.6
now i also have provision for rssi on my frsky v8 rx using made amplifier circuit taking data from the led of the rx as source for signal(installing it as soon as i find proper space).  
things getting installed soon tiny 3 osd and openlrs rx and 808 #16 cam :). no gopro plans for this.
this quad is the best cheap setup i have found for myself for practicing mostly FPV flying through trees etc within 500ft radius(for safety) . i have had aprox 50 or more crashes including 1 being shot by catapult while LOS flying and a few 100-150feet free falls where it lucky fell on grass or mud. i crash every now and then. im using a 7inch monitor (no bluescreen) HMD with 2.5x reading glasses which i installed very recently, fresnel lens going in soon too.  some pics attached below. i dont have any on board video as i broke my 808 keychain cam and no dvr, have only easy cap dvr but no ones got time fo that.  ;D

In the third pic is quad with 2 putt putt boats gifted from VC sir when we met in his place. Thank you sir. I also met Sundaram sir in shillong, thank you sir for the great time. :)

i'd say flash it. there's two worlds difference.  :thumbsup: even in the gains u can double your gains and quad wont wobble a bit.

satyagupta

how do you flash it? any special tools?

take 2 regular servo extensions male and female,take female side and strip the outer cover so that innner pins are exposed and the other male side u remove from the holder and connect each cable to the usb asp correspondingly to the miso mosi etc. and alfemale side align them in the escs pads accordingly. use kk tool to flash. dharmik has also done a very good tutorial in his site.http://rcsci.blogspot.in/

5.8ghz !! please tell me more about that, i want to upgrade my quad too.

pravesh736

5.8 is good as it doesnt interference with 2.4 or gps etc and works well, more like begineers frequency. very easy to tune without having to keep anything away from anything. i have 1.3ghz and 2.3 ghz sets also but their antennaes are too big for this quad and so far haven't had the need to use them as this is penetrating trees also pretty good. hope this helps . do use circular polarized antennaes with 5.8

You can run double the gains and it will not wobble as it would with a normal esc. simonk firmware is optimized firmware for multis, it has faster reponse. it has everything preprogrammed into it, no need to tune any escs either. no LVC either as its better to loose a lipo than a quad. eventually you get a quad thats a lot more stable.  :)
f20a are very easy to flash i have flashed about 16 f20a. 12 with veloci.

veloci

Pravesh, back in bangalore? Great that your got a chance to meet VC and Sundaram sir. You quad looks awesome. Got digital callipers for the antenna build. When shall we begin?
