Learn how to assemble the Frame Arms 035 LX-00 Ray Falx:Re2 1/100 kit with our detailed step-by-step guide, covering preparation, inner frame, armor, and finishing tips.
The Frame Arms 035 LX-00 Ray Falx:Re2 is a striking 1/100 scale kit that combines intricate mechanical design with the versatility of the Frame Arms line. Whether you're a seasoned builder or new to the series, this guide will walk you through every step of the assembly, from unboxing to final touches.
In this step-by-step guide, we'll cover the essential preparation, the inner frame construction, the armor application, and some expert finishing tips to make your Ray Falx:Re2 stand out. We'll also highlight helpful tools and accessories that can enhance your building experience.
Preparation: Tools and Workspace
Before you dive into the build, ensure your workspace is clean and well-lit. You'll need a good pair of nippers for cutting parts from the runners, a hobby knife for cleaning nubs, and a sanding stick or fine-grit sandpaper for smoothing surfaces. A cutting mat is also recommended to protect your desk.
Consider organizing your runners by letter and number to make part retrieval easier. The Frame Arms 035 kit has numerous small parts, so keeping them sorted will save you time and frustration. Also, have some plastic cement on hand if you prefer to glue certain parts for added stability, though the kit is designed to be snap-fit.
- Use a dedicated hobby mat to prevent small parts from rolling away.
- Label your runners with tape and a marker to quickly find parts.
- Keep a parts tray or small containers to hold loose pieces.
Inner Frame Construction: The Core of the Kit
The Ray Falx:Re2 features a fully articulated inner frame that serves as the skeleton for the armor. Start by assembling the torso, which includes the core block and the chest unit. Pay close attention to the orientation of the polycaps—they should be inserted with the correct side facing outward to ensure smooth movement.
Next, move on to the arms and legs. The shoulder joints feature a multi-axis design that allows for a wide range of motion. When attaching the limbs, test the fit before pressing fully to avoid stress marks. If any joint feels too tight, gently sand the peg or apply a tiny amount of silicone grease to reduce friction.
The Frame Arms Extend Arms 07 - Improved HAWK is a great add-on to enhance the articulation of your Ray Falx:Re2. This expansion set provides additional joint parts that can increase the range of motion and stability, making dynamic poses easier to achieve.

- Test each joint's movement before attaching armor to avoid forcing parts.
- Use a hobby file to clean any excess plastic from the inner frame pegs.
Armor Application: Building the Outer Shell
Once the inner frame is complete, it's time to attach the armor pieces. Begin with the chest and head, then work your way down to the arms and legs. The armor is designed to clip onto the frame with minimal effort, but be careful not to apply too much pressure, as some parts are thin and could snap.
For the head, attach the camera eye and the faceplate. The Ray Falx:Re2 has a distinctive visor design that looks great when panel-lined. You can use a fine-tip panel liner to accentuate the details. If you're new to panel lining, practice on a spare runner first.
When assembling the backpack and weaponry, ensure that the connection points are secure. The kit includes a large sniper rifle and a shield that attach via pegs. If you plan to display the kit in a dynamic pose, consider using a base with a support arm to prevent sagging.
- Apply panel liner before assembling the armor to avoid smudging.
- Use a soft cloth to wipe away excess liner for a clean finish.
Finishing Touches: Decals and Topcoat
After the armor is in place, you can apply the included decals. The Ray Falx:Re2 comes with a sheet of marking stickers and water-slide decals. For water-slide decals, use a pair of tweezers and a cotton swab to position them accurately. Allow them to dry completely before applying a topcoat.
A topcoat is essential to protect the decals and give your kit a uniform finish. You can choose between matte, gloss, or semi-gloss depending on your preference. For a realistic military look, a matte topcoat works well. If you prefer a shiny, anime-style finish, go with gloss.
To achieve a professional look, consider using weathering products like the Mr Weathering Color WC18 - Shade Brown. This product can be applied to panel lines and edges to create a subtle shading effect that adds depth to the model. It's easy to use and can be wiped off with a cloth if you make a mistake.

- Apply decals in a well-ventilated area to avoid inhaling fumes.
- Use a toothpick to gently press decals into panel lines for a snug fit.
Display and Pose Ideas
Once your Ray Falx:Re2 is complete, it's time to show it off. The kit's articulation allows for a wide range of poses, from a standing at attention to a dynamic action stance. Use the included base or a third-party action base to support the model in mid-air poses.
Consider pairing your Ray Falx:Re2 with other Frame Arms kits to create a diorama. The Frame Arms #041 JX-25F/RC JI-DAO EA 1/100 is another excellent kit that shares the same scale and can complement your display. Its unique design and color scheme will add variety to your collection.
If you're into customization, you can paint the armor in your own color scheme. The kit's parts are made of ABS plastic, so use a primer designed for ABS to ensure paint adhesion. Acrylic paints, such as those from AK Interactive, work well for hand brushing or airbrushing.
- Use a display case to keep dust off your finished model.
- Experiment with different lighting to highlight the kit's details.
Building the Frame Arms LX-00 Ray Falx:Re2 is a rewarding experience that combines engineering and creativity. By following this guide, you'll be able to assemble a stunning model that showcases the best of the Frame Arms line. Happy building!
