Y6 Copter Build Part 3
Motors M1, M2 and M3 are now ready to be assembled. Use the short screws.
The pictures below show the assembly steps for each motor. Repeat this process three times.

When all motor wires are extended feed through the cables into the carbon tubes and secure them with a piece of tape. The wires for the tail motors should be feed through the square hole in the top plate.

Now take the other three ESC's. Those have to be fitted on the bottom side of the Y6.
M4, M5 and M6 ON BOTTOM SIDE and ESC CONNECTIONS
The wires that come from each ESC have to be connected on the bottom side of the distribution board. That side can be reached via the big hole located on the bottom side of the Y6 frame. Make sure to connect the corresponding wires of each ESC to the correct connections on the PCB board. Solder the wires on the TOP side.

PMU connection to the Power Distribution Board (right side)
Secure the PMU unit using some adhesive tape. And solder the red wire to the + side of the PMU connection on the Power Distribution Board. Repeat this process fro the black wire (- connection). Both wires are approximately 70 mm.

Use the zip ties to secure the three ECS's on the TOP plate.

Now assemble the three ESC's and Y6 Distribution Board onto the TOP plate. Use six nylon spaces to secure the PCB board. Refer to part number below.

Repeat process for M2 and M3.

Now take three ESC's and the Y6 Distribution board. The Y6 Distribution board is a two layer PCB on which the ESC"s connections can be soldered together. Also the connection for the PMU is on the board.

Strip and twist wires into each other before applying solder. Use seperate heatshrink for each wire and one combined heatshrink for all three of the wires. Mark colors in case you use a single coloured wire.
The Y6 multicopter frame is now ready to install the electronic components. Please note that the battery and camera plate will be installed later. Since the ESC's (Electronic Speed Controllers) have to be mounted onto the bottom plate (and top plate) there is less room left when those are assembled prior to the electronics.
First the motor wires have to be extended. Use 18AWG cable to extend the motor wires.

Once finished the motor wires are connected to the each ESC. I used some 2mm gold connectors which I cut into two pieces. One side is soldered into the motor wire and the other side is soldered into each wire of the ESC. Use heatshrink to isolate each individual wire. Refer to pictures below for more details.
Secure all wires with a zip tie. This zip tie should be slided underneath the ESC and TOP/ BOTTOM plate. Repeat this process until all ESC's are connected to each motor. In regards to the rotation direction ; in my case the colors I used for marking the wires earlier are connected as follows:
RED wire -------------> A connection of ESC
BLACK wire -----------> B connection of ESC
BLUE wire -------------->C connection of ESC
RED wire -------------> A connection of ESC
BLACK wire -----------> B connection of ESC
BLUE wire -------------->C connection of ESC
Now its time to assemble the naza board. This carbon board will actually hold the naza flight controller and receiver, and at the same time it covers the power distribution board. During the development phase I planned to have 10 locations to hold this board into place. But since the naza board has only 8, two locations have to be skipped. On those locations I used a three millimeter nylon screw.

Assemble the naza board using four nylon nuts and four nylon bolds.
Assembly of the camera and accu carrier.
The camera and accu carrier is assembled using six aluminium spacers (38mm) that have approximately 9 mm of thread screwed into each spacer. I used long screws and used the Dremel to cut 6 pieces of those screw threads each 18mm long (the 9mm is sticking out of the spacer ). Use loc-tite to secure the spacers.

Now take six vibration damping balls, the battery and camera chassis parts and two Turnigy velcro battery straps. Assemble all parts together. Refer to assembly steps below.
All required parts are shown in the left picture. Two Turnigy Velcro battery straps, six vibration damping balls, the battery and camera chassis part (Pavako) and finally on the right side the carrier chassis part that will be screwed onto the six aluminium spacers. In this design the velco straps should hold the battery in place. To make sure the battery is not sliding a lot, it is recommended to used some pieces of velco in between the battery and the battery plate.
Velco straps slided through the slots.
Vibration damping balls in place
