Quad Copters and Drones have come such a long since I looked at them. It’s easily been 6 years since I was interested in quad copters. Based on all the advances I can’t even call them that anymore. They really are drones. Actually, UAV (unmanned aerial vehicles) are what I’m talking about and I’m buying some to find out their capabilities. I think I’m going to get certified.
DJI has some really awesome drones. They are a good idea of cutting technology on a piece of hardware. They are a bit expensive but they look like they are worth it.
Beagle Drones seem descent but more research is required,
I like what onpoynt is doing, offering the drone creating (3D printing) & training. They have much going.
