Hello
I used this method.
It is interesting if ESCs are powered by Power management board.
You can also connect directly the “ESC” on splitter board wich it is content in the package (See close M4).
This second case is useful, if the ESC are powerded by the main board of the frame (example : Tarot 650 Sport).
I preferd isolated the connectors under protection thermoretractable.
