I started my drone experience with the phantom 3 standard, then did the accessories thing, extra battery, more props, camera protection, upgraded phone attachment point and antenna mod.
Then I thought I had done all I could and I wanted more so I sold my like new standard on ebay (I am serious I used to clean and polish everything after each flight, no scuff marks)
With proceeds from sale I purchased phantom 3 advanced, also used but mint but I really don't need to accessorize because came with 3 batteries, extra props, prop balancer, anti glare hood, prop protectors, hard shell backpack, CF camera protector, camera filters.
Only thing I will get is some type of antenna mod.
When I get to the point where I can't stand not having a phantom 4 I will sell this kit on ebay and get a phantom 4, my point after all this story is I am not one of those guys you see that have 3 or 4 ships, can't really afford it and I am ok with. The one, I treat this baby like it was worth $5,000 dollars, clean and shine after each outing and I don't take chances if I get a warning I land.
I am sort of attached to my ship.
