Tools
1. Soldering gun

2. Soldering wire

3. Soldering paste

4. Plier

5. Hot glue gun

6.Hot glue rods

7.UHU por glue

Making process
1. Cutting four A,B,C and D type of ice cream sticks as the drawing.

2.Assemble four sticks together as the drawing with glue.
3.Cutting future board as the drawing.

4.Attach assembled ABCD sticks with finishing cut future board by UHU por glue. 
5.Making camera base by future board,using wooden rod for camera rubber band fastening.
6.Fixing base on X main frame by hot glue gun.(see picture)

7.Soldering low ESR capacitor to flight controller main power port.
8.Soldering battery cable connector to flight controller main power port.
9.Attach flight controller on X main frame by shock absorbing glue tape.
10.Wiring and soldering micro receiver with flight controller.
11.Wiring and soldering four coreless motors as following layout.

12.Wrapping up electrical tape on every coreless motors to prevent heat glue melting.
13.Using cable ties to fix every motors in their places.
14.Glueing every 720 coreless motors by hot glue gun.
15.Updating firmware of flight controller by Betaflight App.Adding AUX switches to select flight mode-Angle,Acro and Air mode.Normally,do not need to adjust PID setting and motor setting.The micro receiver signal can be set to PPM or SBUS.If the controller can be armed ,it's ok.If not ,problems can be solved by search engine or YouTube.
