15mm ZMR unibody spacer 3mm arms with shortened standoffs

pinshape

This is a robust ZMR 250 spacer designed to serve as a single unit, with all components nestled between its two bottom plates. By expanding the spacer from 10 to 15mms and reducing arm mounts from four holes to just two, this design offers several key advantages. More interior space becomes available for incorporating additional components, resulting in a lighter overall weight. This modification also significantly reduces print time, enabling faster production of your ZMR 250. Moreover, by bolting arms directly into the inner two holes on the bottom frame, you enhance rigidity and further minimize weight from lengthy bolts. This streamlined approach optimizes performance while keeping the build as light as possible. The small backstop, which fits snugly over spacers, serves a critical function: it prevents batteries from sliding into FPV pods during crashes, safeguarding your equipment. This feature is particularly useful for builds similar to yours, where battery safety is paramount.
