Mini 4WD MS Flex Anti-Bow Underplate Processing Jig Tool Prevents Gear Mesh Instability After MS Flex Chassis Completion, Stabilizes Drive [Free Shipping] MS Flex Anti-Bow Underplate Processing Jig Tool Prevents Gear Mesh Instability After MS Flex Chassis Completion! Stabilizes Drive! This is a jig tool for manufacturing reinforcement parts for the chassis undersection during MS Flex production. The jig's strength has been increased. [Shimizu Manufacturing & Repair Workshop] After MS Flex completion, the front, center, and rear sections split into three parts, causing a drooping state (bowing phenomenon). In this state, the gears between the chassis separate, causing poor meshing, unstable drive, and ultimately, a reduction in speed. Furthermore, if the front and rear units bow, the thrust angle of the front and rear rollers changes, and the expected performance may not be achieved. The anti-bow plate solves these problems. The plates that can be produced are the three types shown in the image. Depending on the plate used, there may be some play when setting it in the jig tool, resulting in a loose plate. In that case, fix it with screws when setting it and confirm that it does not move before cutting with a saw, etc. It is recommended to use a thin-blade saw, such as the "Tamiya Craft Tools Thin-Blade Craft Saw," for cutting. This product is manufactured using a 3D printer. There are no problems with its intended use, but the color may differ from the image, or the shape may be slightly different. Please understand.
