The Hubsan X4 is personally my favorite (small) beginner drone. It’s about the same size as the Nano QX, but roughly half of the price. There’s 4 different versions of the Hubsan X4.
The cheapest version is about $45 USD (including the controller). It 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 next 2 versions of the Hubsan X4 have cameras. They’re slightly bigger and heavier than the cheaper version of the X4, but the flight time is about the same. The H107C is the version with a standard definition camera and the 61170-02 is the one with a 720p camera. The Hubsan X4 with the standard camera is ok, but the 720p camera takes much better video. The only problem with the HD version is that it’s more expensive and the flight time is slightly less.
The most expensive version of the Hubsan X4 is the H107D. It’s mainly for FPV, which allows you to see everything that the drone can see in real time. The design is slightly different from any of the other models and it has a black antenna on the bottom. Although FPV is really cool, this is probably my least favorite version of the Hubsan X4, mainly because the flight time isn’t as good as the other models and the FPV range is only a couple hundred feet. It’s also about 2 times more expensive than the Hubsan with the HD camera.
