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.

@ sooraj...
thnks...
done the laser cutting locally here....its charges around 100 Indian Rupees for both plates @ 10 Indian Rupees 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 Indian Rupees for 4x6 sq ft..
cheap for R&D...n ecofriendly..

Retreat, Hell!



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!

Nice build but dude add something in between those 2 copper boards. If anything shorts those 2 plates then boom and smoke...

Hot glue or nice big blob of fevicol.

instead of drilling i prefered heating a small metal rod...
arranged the arm and steering assembly... inserted hot metal inside the plastic...
got the insertion, then i tightened the servo mounting screw ...some inside material came off..
carefully removed the spilled out plastic mass...

with the help of servo mounting screw and four head screw driver. after tightening pour some CA for extra strength..

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.
