Hi folks,

this is my first build thread here, I started it to make myself document my second heavy lifting project for AP work.

Components I will be using are following;


"Top part" of multirotor:
FC: Wookong M
Motors: Tiger MT3515-15 x8
ESC: KW60E x8
Distro board: Gryphone Distro board with dual BEC
Prop: Xoar 15x5 + 8mm to 6mm reduction x8
Battery: GensAce 10 000mAh 6S with EC5 connectors - already have few, will update my supplies as soon as we get maiden :tennis:
Tx/Rx: Graupner GR-16 paired with Graupner MX-20
LED set and other accessories..
Still thinking about adding 2.4GHz DJI Data link which I have (50 waypoints) and DJI iOSD since I have them at home but not sure if I really need them for start..

"Bottom part" of multirotor:
Gimbal: 3 axis cinestar style gimbal produced by us (Using 2 motors on each axis connected on 3 alexmos boards, every IMU from board is on its own axis for better results as seen on Flexacopter BDD - thank you Mario for idea :tennis:)
FPV: 5.8GHz 500mW Boscam with Cloverleaf antenna
Tx/Rx: 2.4GHz Assan for camera guy

Frame:
In house made! Yeah, we spent over few weeks to design frame for our X8. Good friend of mine is SolidWorks expert so I had chance to work with him and make ultimate frame designed specially for our components. You can see few screenshots of drawings, but take a note that these are not finals!

Some specifications of the frame: 25mm PA6 clamps, dual motor mounts made of alluminium, side battery try, bottom ESC and power distribution mount board (they are far far away from electronics - you can never know!), plate for IMU mounting, top plate for GPS mounting, 2 stage antivibration system using custom dumpening material, etc., etc...


This is it for the first post, we are starting our CNC router by the end of this week ( waiting for some parts to arrive :upset: ).. If I forgot something, will add it in the second part.

Greets to all from Croatia!

Some of the process has been made... :)

Here are two pictures, first one - cutting carbon fiber on CNC and on second one are center plates with three levels for electronic. I am in doubt about last one since it is only GPS mount, maybe GPS will go on the arm?!

Still waiting for the booms to arrive, they should be here tommorow so then I will start soldering motors and ESCs. More pictures coming soon :)

Greets,
Nikola
