We have created a product that is affordable and allows beginners and those who want to easily try MS Flex to build a solid chassis. While it may not be as good as some of the more expensive products, we have paid close attention to the materials and layering. Regarding the price, we have 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 with the necessary licenses and permissions. 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 have designed the shape to make it easy to create clean cutting lines, even for those unfamiliar with the work. Also, unlike other products, it has a structure that firmly holds the chassis, allowing you to create a flex chassis with high precision. There may be layer lines characteristic of 3D printers, but this does not affect 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 carefully explain how to use it until the end, so thank you for your support. license Designed by kosuyoung pro. Thanks to your good designs.
