The Hubsan X4 makes the number four spot on our list. On the other end of the spectrum of affordable drones, the Husban X4 offers what few others in its category can.  The first thing you'll notice is its size, as the Husban X4 is hardly bigger than a standard smart phone. Due to its smaller frame and lighter weight, this tiny drone is best when used indoors, or outside on a calm day with no wind, as it could get carried away by any particularly large gusts.
You can pair the Tello with a third-party gamepad controller, but it’s easy enough to fly using the simple, intuitive Tello app. Thanks to its link with DJI (the Tello’s flight controller is made by the drone manufacturer), it’s a great ‘first drone’ for kids or adults looking for a learner model to practice on before moving to a bigger quadcopter like the the DJI Mavic Air.
With an altitude hold mode, which keeps the drone at a specified altitude, the Yanni Syma can hover, ascend, and descend at the push of a button, making this one of the easier drones to manipulate in the air once you get the hang of it. At the same time, the Yanni does have similar downsides in terms of charging time, flight distance, and flight time. It takes over two hours to charge, can travel to fifty meters away, and its battery can last for up to ten minutes of flying time. Even with all of these faults in mind, it would be hard to do worse, considering all that you get with it. Best recommended for the more serious beginner interested in FPV drone racing.
