I want to build a drone, with a RasPi, sense hat, and the RPi camera. So what I want is to be able to send the data (preferably without having to buy, like, cell service or something), without lag, for the FPV. So I would need to send commands to the drone's pi, and receive pics back from it. And with wifi or bluetooth, like the ones you can buy, the range isn't great and if the drone goes to far, the FPV lags out. If there's a way to get a bigger distance, that would be great, but if i'm asking for something dumb, and far-fetched, please tell me so. I don't have much, (if any), experience in this area of computing.
Aim for perfect and you'll hit somewhere near pretty good. (maybe...)
