Wanting to get into the drones. Not sure where to start. I have a small nano drone that I'm trying to work with in order to get used to flying a quadcopter cuz I have never controlled a helicopter of any sort of plane. I've heard the small drones are harder to fly than the bigger drones. Is that true? If so where can I start. I like the dji phantom 2 plus vision a lot but as well as the phantom 3. Any help is appreciated in getting started.
