My name is Richard I'm 67 yrs old and just got into this hobby. I have a question for someone that can advise me about basic droning. My question is can you use your cell phone as your drone monitor without a wifi connection. I have a Bugs B4W with SD card slot and want to take pics and video in remote places. I know I can take pics and video without wifi but how do you monitor your flight if the cell screen wont work without wifi, or if it will work how to do it
