Futaba 9Z and CamPac

You can only use models that are on the card if the card is in the radio. Think of it as a floppy disk for your computer. Once you copy it to the radios standard 10 model memory then you can remove the card.
You can use the copy model function to copy to and from the card, or you can just start a new model from scratch right on the card.
It is just like a disk, the data is always there until you erase it. Once you get it in the radio and play around with it you will get it. It is very simple once you see it work. I just got my CAMPac not too long ago and I love it. Also beleive it or not but you CAN copy between the old 9ZAP and the latest 9ZAWC2.
If you have any more questions keep asking I will try and answer them.
