Banggood.com’s Eachine brand comes up with some interesting quadcopter drones and accessories; the inverted-flight enabled Eachine 3D X4 is certainly on top of that list. It turns out that the 3D X4 is in fact a JY004A quadcopter drone, which just got listed on GeekBuying.com for a little over $27.
The JY004A too does inverted flights, and it sure as hell does look like the Blade Nano QX 3D. What differentiates the JY004A quadcopter from the Eachine 3D X4 though, is the fact that every JY004A comes with two canopies, and it is yet cheaper than the 3D X4.
The JY004A does headless flights (click here to know what it means) and offers one key return. According to the product page, the quadcopter drone has a 150mAh battery which returns 6-8 minute flights.
Here’s a little video of the JY004A:
