Yep, and the reason is... they were used up. The first generation M400 had arms with no ties to secure the wires next to the comm, and they were soldered connection. So what do you think happened?One thing I never come across are those black Mura endbells made to fit the Mabuchi cans. There are seemingly a fair amount of the Tradeship ones still out there NOS, but the Muras don't seem to be around...even old and mangled.
They were made of much better plastic. The Mabuchi endbells were made of cheap Delrin that melts when water boils... the black Mura endbells were made of a fairly low-temp phenolic plastic, but still much better than Mabuchi's. The second generation in while phenolic material was MUCH better.Were they also of a better quality plastic or just the same stuff as the Mabuchis molded in black with the Mura name on them?
No, Mura made their own but they were copied right from the Mabuchi stuff. The Mura hardware used a brush holder retainer made from copper (Mabuchi used plated steel) and the brush holders were brass extrusions (Mabuchi's were plated sintered steel).Was the hardware the same as the Mabuchis? I'm guessing that they were sold separately as upgrades for motor builders?
Mura's second generation used a copy of the Champion pent-roof brush holder retainers and the same brush holders. When Cukras and Zimmerman figured out that you could use the FT36D brush holders and larger brushes, Mura went one further and developed the stamped copper "square" brush holder that is the same as used today.
