with the help of my HOT AIR GUN
this modification will help in tight motor mounting grip via zip ties and will reduce some vibration too from spinning motor...
(http://i935.photobucket.com/albums/ad200/commonon/20141217_223700_zps2034f861.jpg) (http://s935.photobucket.com/user/commonon/media/20141217_223700_zps2034f861.jpg.html)

done shrinking to all 3 booms

make sure u drill the holes exactly perpendicular....otherwise u may not find the booms in one plane when streched....thus motors wont b mounted perpendicular....

im trying to make the pics as self explanatory... so plz omit if i go wrong in yours opinion.

center plates n their modification

(http://i935.photobucket.com/albums/ad200/commonon/20141217_233545_zpse09ea9f6.jpg) (http://s935.photobucket.com/user/commonon/media/20141217_233545_zpse09ea9f6.jpg.html)

drill hole exactly in the centre of 1,2,3 & 4. as in pic

Best of luck :thumbsup:

Where did you laser cut the ply center plates ? How much does it cost ?
Why did you chose plywood - as it is cheap ???

@ sooraj...
thnks...
done the laser cutting locally here....its charges around 100 :Rs: for both plates @ 10 :Rs: per min...

i do have carbon fibre , g10 sheets
but i choose ply coz its good to use wooden, easy available,can be easily n cheaply replaced on crashes ,can bring any mods on ones requirement on ply ,cheap 600 :Rs: for 4x6 sq ft..
cheap for R&D...n ecofriendly..

drilled the top plate

Expecting a good explanation on yaw mechanism .

Hi Manish!

I just maidened my 360 Quad (APM 2.6). Flies great!
I'll be doing some trimming and fine-tuning later today.

It'll be really awesome if we could get together for flying!

asssembled all

Hot glue or nice big blob of fevicol.

the most important part rudder mech

neat and detailed build log  {:)}  {:)}  :hatsoff:

carefully removed the spilled out plastic mass...

about my ESC's
im using simonk firmware
how to do flashing is explained in the above thread....
cut the esc wire of motor side so that no excess wire lenght should b there

Hi manish,

I think the yaw could be little weaker in your setup. especially the arm connecting the motor hinge.
though this might not completely put your copter down, it might surely create problem, you could use my setup here.
sand the side of the nose gear mount and the arm and stick both of them together with medium cyano.
See pics.

great job.. :thumbsup:

@Ashok sir, White props!!  (:|~ Where can I get those ?

white props from Satyagupta,
btw, now using std orange and green for more visiblity.

Wow cyromanish great DIY , waiting to see the flight   :thumbsup:

mounted the prop, motors n esc in its place,,, used thin zip ties
