ESC connection diagram
ESC connection via 8 pin connector
For easy ESC connection via 8 pin cable
FETtec FC G4 - N to FETtec 4in1 ESC 45A (same for FETtec 4in1 ESC 35A), cable included
with FETtec ESCs.
Any other ESC is usable (please make sure the signal pinout is correct, otherwise change
accordingly
Page 9
Single ESC connection diagram
The FETtec FC G4 - N provides 4 ESC signal pads for solder connection of single ESCs
