Motor Mount Heatsink for YD2R/RMC purple

This is an aluminum motor mount with a heat sink design, compatible with rear-motor setups. Compared to the standard motor mount, it has heat dissipation fins, increasing the surface area and thus improving heat dissipation. It's especially ideal for rear-motor setups where airflow during operation is limited. It has seven mounting positions on the gearbox, allowing you to change the motor height around the top shaft axis. The mounting holes have been increased to allow for even lower motor positions than the standard six positions on the YD-2R, expanding the range of settings.
