Thanks for the pdf file Peter. I think my confusion is based on the photo in RCM&E where your motor wires are fed from the motor through the top small hole in F1, not the large oval hole. I don't think that an ESC would go through that hole? The installation description also refers to the ESC being "fed through from the cockpit and sits on top of the battery platform". Sorry to be persistent but this may confuse others too?
