The mgm manual is a breaze, I had my mgm calibrated and fully programed via the transmitter in less than 5 minutes if even that long. Mike also agree's with me...both him and I have the usb module and connection cables for the pc but never use em cause its just as fast or faster to use the transmitter! Anyway I want that big z series esc for a 50'' bonzi conversion I want plus I want one for my baja project.
