Oldcat, I want to clarify that in any material; alu, brass, or pc, they each will have "esc 4xrgb leds", "3 leds + light diffuser", and "8 underglow smd leds"? Because in the diagram you shared, for example, only the "esc 4xrgb leds" is present in the black pcb but not in others. Thanks for the clarification.
BR,
Yohannes
