So this is pretty much the connection diagram:
with the addition of the FPV, but that takes it’s power directly from the battery connector on the PDB.
This is the (relevant) kitlist:
4 x ChaosFPV CF225 2300Kv Motor (2 x CW, 2 x CCW)
4 x Chaos BLHeli_S 25A ESC
1 x SP F3 Flight Controller (Acro)
1 x Mini 5V BEC
However, most of that is connected to the PDB.
