No knowledge about drones, I just picked this up on trade from a buddy that does commercial drone work and he needed his truck fixed, so I got him on the road and he gave me this complicated piece of machinery. I need it sold though, holidays are slowing my work and I could really use the extra money to give the family a better holiday. This drone has great reviews, 4.4 out of 5 stars. Comes with 2 batteries, SD card, extra propellers/blades, phone mount, charger, and all the paperwork to get you on the app in the right direction to fly and do what you want with it...$100.00 OBO
