New here, am interested in purchasing my first drone! Was hoping someone could help me out here. After a lot of searching and researching, I've narrowed my choice to either the Hubsan H502S, H501S, or the new H501A. I know the H502S is a cheaper model of the H501, however I can't seem to find the differences between the H501S and H501A. I saw the 501A has wifi FPV, however wouldn't that have a more limited range? Also, does anyone know if there are other differences between the 501S and 501A? No matter how much I read, I can't seem to figure out the differences other than the controllers and that the 501A has "waypoints". However the 501A is priced cheaper, while being a lot newer. This is making it hard to figure out which to buy! Thank you in advance!
