There’s a few different versions of the Hubsan X4. The cheapest version doesn’t have an agility mode like the Nano QX so you can’t fly with complete manual control, but it’s pretty fast and maneuverable (even with auto leveling). It also has 6 LED lights which can be turned on and off from the controller. Speaking of controllers, the controller that comes with the 3 cheaper Hubsan models is actually pretty nice. I like it better than what comes with the Nano QX and the Proto x).
The EVO from Autel Robotics is clearly copying the DJI Mavic series, but surprisingly this is more than just a subpar clone. Clearly the styling a little different from the Mavic 2 or Mavic Air. Just like the last drone Autel Robotics made (the X-Star Premium) the design of this thing looks very strange in my opinion. It comes in this bright orange color which is great for visibility, but some might argue it looks like a cheesy toy. Other than the color, the general design is pretty good. It folds into a small shape and has a full 3 axis gimbal just like the Mavic.
Removable cameras: In some models, users can remove the cameras and fly the drone without the camera attached, excellent if this is a gift for a beginner who still needs to learn to fly. This helps to reduce the weight of the drone, thus enabling longer flights. More importantly, this feature enables camera upgrades when there are advances in the technology. Perhaps your gift to mom or dad next year will be just such an upgrade.

2) the instructions are ridiculously basic. Not sure if they were written by someone who's not English fluent, but we were able to figure it out. They don't address the camera at all. You'll be able to figure out where the camera attaches by process of elimination (on the bottom), and the big USB has one of the tiny USBs inside that goes into the camera (I'm sure there are real words for those pieces that I don't know!).
What it does have is everything you need to start flying (seriously). When you buy the Vision 250, there’s nothing else you need to buy. You don’t need to worry about battery chargers, controllers, goggles, receivers or anything at all. It comes with everything you need including FPV goggles and a controller for just $350. That’s less money than a set of pro FPV goggles!
The Phantom 3 Pro shoots video at 4K, 3820 x 2160 pixels on a fully stabilized, 3-axis gimbal. You can shoot 4K videos of up to 30 fps and take 12 MP photos. Besides, it has a vision positioning system enabling a stable flight experience indoors as well, whereby you can fly it low to the ground in GPS free areas. Live viewing at 720 pixels is possible with Lightbridge digital streaming, along with full-resolution videos getting recorded in the microSD card. It also comes along with a flight battery and remote control that is rechargeable.
This is a nice sturdy and attractive quadcopter for the price with a lot of features only found in the more expensive drones. It’s good for beginners and intermediate pilots, but not recommended for those wanting to take professional video and photography. It doesn’t have any of the features that make a good video drone, like stabilized video, low video compression, or just having control over the camera settings.
The DJI Mavic Air offers a 32MP sensor, 4K video capability up to 30 fps, and fully panoramic image functions. There’s a 3-axis gimbal for stability when filming in flight, and there’s some pretty detailed environment sensing to help the drone get its bearings while flying. The model delivers up to 21 minutes of flight time, which is on par with much of the mid-to-pro-level drone market. There’s 8GB of onboard storage, HDR capabilities, and more.
