Hello, we're Team THIRDEYE ROBOTICS.
Today, we're going to introduce the Airframe Assembly-Body episode as the fourth session.
1. Rear pusher motor, motor mount tightening
You can use the screws included with the TMOTOR product.
Use loctite 263 (red) for screw retainer and fix the screw completely.
2. Working with canopy mount parts and removable parts
The canopy is divided into three parts: front, middle, and rear.
First, attach the body of the intermediate canopy and the plastic part that can be opened and closed using UHU bond.
There was a problem in the production process, so the back of the canopy needs some processing.
The EPO hole in the area where the plastic part is to be inserted is deeper than planned, so please proceed with the work and attach the plastic part using a UHU bond.
* Maintain for 24 hours after attachment
3. Attaching Body Basic Plastic Parts
For the body work, you can work on the plastic parts used in the battery connection, camera mount, and rear canopy mount as shown in the video.
* Maintain for 24 hours after attachment (Do not tighten the camera mount and screw immediately). Please allow 24 hours to work.)
4. Attach Camera Mount Plastic Parts
There are two types of camera mounts.
It consists of one Sony A7 series a6000 series mount, and one mount that can be compatible with various camera equipment.
You just need to do a UHU bond with a plastic part that can be threaded and fastened on the two mounts.
* Maintain for 24 hours after attachment (do not tighten the body and screw immediately. Please allow 24 hours to work.)
5. Body Reinforcement Air Plywood Assembly Work
The carbon pipe connecting the wing to the torso can be twisted due to the influence of motor thrust and external wind. To reinforce this, aircraft plywood is used to reinforce connections.
First of all, please work on the aircraft plywood on the camera mount side so that it does not twist using instantaneous adhesive.
6. Work on torso, reinforced plywood and torso carbon pipes
Please check where the reinforcing plywood is attached and proceed with the body and reinforcing plywood first.
In this process, pass through the carbon pipe so that it can be attached to the correct position.
Keep the length of both sides of the carbon pipe at 269mm relative to the body, and attach the body and the carbon pipe through UHU bond.
Finally, apply instantaneous adhesive to the reinforcing plywood and carbon pipes, and instantaneous adhesive work to the connection between the battery-mounted plastic parts and the aviation plywood parts.
7. Rear motor mount to torso
A carbon pipe reinforcement is incorporated between the rear motor mount and the torso.
You can attach it to each part by working on it.
This part needs a strong connection, so please keep it for 24 hours after attaching it.
8. Rear Motor Transmission (ESC) Body Attachment
* The three-wire servo line was originally intended to make a receiver extension connection, but it was moved to a different location and was excluded from the operation. Please take out the 3rd line servo line from the part of the video.
Attach the transmission to the EPO part separated at the bottom of the body with double-sided adhesive as shown in the video, work on the motor mount side and the back of the body so that the line can fall out, and attach the EPO part using the right hood. It is recommended that batteries or heavy parts be placed on top for strong attachment.
* Maintain for 24 hours after attachment
9. ESC line to wing, wing servo extension and torso EPO attachment
Extend the three ESC power lines (+2 lines, -1 lines), three ESC signals (two lines before and after the transmission, - one line on the ground), and three lines of wing servo to connect to FC and main power.
*The servo extension and power extension are included in the KIT product. You can work with the included product.
And after marking several lines, attach the separated body EPO part like a video.
(Power wire - one marked, wing servo three marked, name sticker attached)
10. Body to wing plastic attachment work
Attach the plastic parts for fastening the body and wings with the body.
Please keep it for 24 hours after attaching it.
(Never combine them with wings until they are completely dry.)
11. Working with Body Electrical Connectors
The torso connector uses a female connector opposite the wing connector.
Check the solder wiring on the wing again and work on it.
Work on the three wing servo wires and the three transmission wires together as shown in the picture above.
Also, if you look closely at the DSUB pin, the numbers are written. It's from 1 to 10.
Number 1, 3, and 5 are wing servo lines, number 1 is signal (white/yellow), number 3 is + (red), and number 5 is -ground (black).
Number 6, 8 and 10 work on the 3 transmission lines, number 6 front transmission signal (white), number 8 rear transmission signal (white), number 10 - ground (black).
12. ESC Power Line Operation
Bundle four quad motor ESC wires and one rear motor transmission to connect the +, - main power line.
+ For power connection, please add 4 Quad ESC and 1 Rear Transmission, plus 1 BEC + 1 wire to tie a total of 6 wires.
- For low-power connections, please tie 4 wires by adding BEC - 1 wire in addition to 2 quad transmission and 1 late transmission.
And you can connect it to the FC power distributor.
* Be careful not to heat the EPO while performing the shrink fabric operation on the pre-worked part. (EPO deformation may occur due to heat.)
13. BEC line distribution operation
The BEC uses three currents: wing servo power support (6V), telemetry equipment power support (SIYI HM30 AIR part / 12V), and EMLID REACH M2 power support (5V).
For VTX, please change 6V through soldering. (Check the website of the Matek board)
The 12V then uses SIYI connections to solder, the 5V 3-wire servo line to cut the signal line and cut the spare length to solder, and the 6V power line to a length to work on the FC servo line connection.
14. Working with BEC Main Power Line
Connect the +/- wire that was disconnected during the ESC and power distributor work to the BEC.
Please adjust the length of the line so that there is no interference with the FC position in the future as shown in the video.
And attach the BEC to the location shown in the video using double-sided tape.
15. Check rear motor 3 wire operation and motor orientation
The rear motor uses CW (clockwise) when using the propeller, so you need to check the direction of the motor and do three-wire soldering.
One of the three lines should be soldered and shrink-proof.
The other two wires are soldered at random, then placed on the 2200 using a servo tester and connected to the main battery.
This will result in transmission calibration, which will be completed by lowering the servo tester to 800. After that, if it's higher than 800, the motor turns.
Check the direction of the motor in the process of Do, and if the direction is correct, do the shrink cloth immediately. If not, change the other two lines, do the soldering again, and do the shrink cloth work.
16. Close rear motor mount cover
The rear motor mount engagement screw is an M3 X 12 wrench bolt.
The rear motor 3 wires are complete and the cover is closed. Please work carefully so that the third line is covered without interference during the closing process.
And please use a screw retainer when fastening the screws. Loktite 242 (blue liquid)
17. FC anti-vibration mount operation
EPO is less rigid than carbon and composite, which causes vibration. So, rather than attaching FC right away, I recommend that you use FC anti-vibration parts.
Please check the center of the airframe and attach it.
18. 3 wire connector pin operation to FC
Please adjust the length of the line so that the three-wire connector pins separated during ESC work can be connected to the FC.
For the left ESC 3 line, combine one front ESC signal line, and the -ground behind ESC signal line to work on the other and solder it.
19. I2C Extension Board Line Extension Operation
The I2C extension board is a product that includes FC, and it is recommended to use the air speed sensor and the external compass as it can be extended at once.
If another FC is used and there is no I2C extension board, the air speed sensor and the external compass lines must be extended separately.
20. Attach air speed sensor, attach external compass sensor
The air speed sensor has a space to attach to the lower left side of the torso. Please check the direction carefully through the video and work on it.
Since the external compass sensor has the FC in the same position as the main power line and the BEC, high current may cause flight problems when using the FC compass or compass attached to the canopy. So the external compass is placed where there is no current as much as possible.

21. Battery space reinforcement work
There is one product left that has not been worked on among the air plywood. You can use this product like in the video to apply UHU glue and instantaneous glue.
22. Back canopy GPS work, Telemetry AIR attachment work
Please attach GPS to the back canopy with a woo-hoo bond like the image. Please check the GPS direction carefully and attach it.
Attach the telemetry (SIYI HM30 AIR unit) equipment to the inside of the canopy by working on the UHU bond like a video.
In the future, antenna wires will be attached using a 3D printer.
23. Camera mount torso connection and front canopy bond operation
The camera mount fastening screw is an M3 X 30 wrench bolt.
Please use a hand tool when fastening the camera mount. Power tools may damage the mount.
Lastly, attach the canopy on both sides evenly.
* Maintain for 24 hours after attachment
That's it for the body production.
I will share the work of the controller receiver while setting up the FC. Please keep that in mind.
I'll be back with the "FC Setting" content soon.
