You could build your own fpv quad for quite a bit less than the price of a phantom 3 advanced, "IF" you have the time, patience, knowledge, and required tools. I started out with 3 ready to fly quads, then as I began to do research on how they work, and all the different components available, I got into building my own from kits, a frame here, motors there, esc's, transmitter, batteries, chargers, etc. etc. It can be REAL frustrating at times, but also REAL rewarding, when you get one all built, tuned, and flying like you want it to. I'd suggest LOT'S of reading on forums like this one, and others, before you start buying though. Just my opinion. And beware, it's ADDICTIVE for sure!
