Flysky PL18 Ultra + Crossfire Expansion Module

To make the Flysky PL18 Ultra easier to carry and use, I designed this expansion module, which allows the PL18 Ultra + Crossfire combination to fit into the original foam case provided by Flysky and significantly improves the user experience. This module will not damage the device and is very convenient to use, but you still need to purchase a few accessories (total value not exceeding 20 yuan). The list is as follows:

1. 5-pin 2.5mm pitch high-power battery connector, blade terminals, 90° side-entry male plug

2. 5023800600 connector (The Crossfire kit should include the corresponding connecting wire; you need to cut other wires and only keep the CRSF signal wire)

3. 5023800300 connector (The Crossfire kit should include the corresponding connecting wire; you need to cut other wires and only keep the power+ and power- lines)

4. M2.5*8 cup head screws *4

You will need to insert the plug into the adapter part, which may require a little force, and solder the power+, power-, and CRSF signal wires to the corresponding ports (a wiring diagram is included in the assembly guide). You can use any Bambu Lab printer and material for printing, but I still recommend using PTEG or PLA filament for printing! If you encounter any installation issues, please describe them in the comments section.
