Guys,
If the user has iFly Streets on it, the card can become full. Using iFly Connect or using the Wi-Fi of the iFly 720, it will automatically detect the card is getting full and suggest to remove some options like Alaska, IFR Data, NorthWest, SouthWest, NorthEast, ect. Just chose what you plan to not us in the future. If can always be added later.
If you don't have iFly Streets, is really simple. Just copy all files and folders from the 8gb SD card and paste those onto a new 16gb SD card. That is it.
As for Sticky's, our forum does not support the "Sticky", however we can pin a thread to the top of a forum. Much the same concept, but we are more looking to adding Video Tutorials under the Support tab. Our is not moderated and not really promoted for Official Support, more for discussion and owner based support. However, you will find iFly Staff on here a lot. I hope this helps.
