This is an affordable, all in one option for an indoor / backyard FPV drone. It comes with a screen, a controller with several functions, and a drone with a built in HD camera that transmits back to the screen.
I love flying fpv, so I tested it out inside and outside in my backyard. The range and signal was fine for my tiny yard, and I expect it would be fun in a small park setting too. The video screen seems bright enough, although I was in the shade. The E40 flies like many of the other indoor, whoop style drones. It has 3 flight modes, and you probably want to have it in the most aggressive mode if you are going to be flying it outside. Also, I want to remove the prop guards because they look awful, but I will leave them on for testing.
The top left shoulder button on the remote control takes a picture with a quick press and starts video with a long press. The next part of the review will be more in depth. If you want to buy this ~$40usd indoor fpv drone, you can click the following link: Eachine E40.
I will do a more detailed post soon that will test out the HD camera capabilities in a following post.
