We've created a product that allows beginners and those who want to easily try MS FlEX to build a solid chassis while keeping the price down. While it may not be as good as some of the more expensive products, we've paid close attention to the materials and layering. Regarding the price, we've lowered the profit margin to make it more affordable. This is an original jig for processing MS FlEX chassis, produced with a 3D printer. This design is from a Korean racer, and we are now able to sell it because we have obtained the necessary licenses. For processing, we recommend a thin-blade craft saw, such as those made by Tamiya, but any saw blade with a blade width of around 0.25mm can be used. We've designed the shape to make it easy to create clean cutting lines, even for those unfamiliar with the work. Also, unlike other products, this structure firmly holds the chassis, allowing you to create a highly accurate FlEX. There may be layer lines typical of 3D printing, but this does not affect the use. In addition to this product, you will also need a saw, nippers, etc., for the build. Please use with caution and pay close attention to safety. If you need instructions on how to build it, please let us know in the transaction comments. We will explain how to use it carefully until the end, so thank you for your support. license Designed by kosuyoung pro. Thanks to your good designs.
