The XK x1 does come with proprietary batteries, that are semi-smart ones, showing how much battery is left on the actual battery with LEDs.
The maximum advertised battery life is about 17 minutes, but in real life scenarios expect 15 minutes maximum, which is still plenty for such a drone.
The battery is 7.6v 2200mAh and I would strongly advise you to get the package with at least 2 batteries, because getting them afterwards might be impossible, as shipping batteries separately from china is prohibited in most countries.
Yes, the Xk x1 will return home if it loses signal and what's more, the app will regain the video signal as it gets back in range. This is something that most drones don't do, and you'd have to restart the app itself to regain the video feed.
These two drones are quite similar in looks and features, however, the JJRC Aircus does have some fuzzier footage compared to the X1.
I feel like the X1 is probably one of the best drones for the price and you should definitely get it instead the Aircus, especially since they're both about the same price.
I have situated the Xk X1 under the $200 category, as I find it's the best way to separate drones in these lower price ranges.
Bellow are some of it's competitors, you can add each of them to compare and then press the "compare" button on the right to go and compare their specs.
The gimbal is a 2 axis one, which means it's quite stable, but if you move the drone left to right, you might see some jello.
I can't stress enough the importance of a good gimbal, and thanks to the amazing gimbal this drone has, it does make the top of my list for 2020.
The camera can be turned up or down, but incrementally by pressing two buttons, instead of a scroll wheel, which is a bit of an inconvenience, but it's a system that probably makes the drone cheaper.
One thing to compensate is the Micro SD card slot, which means you'll be able to record the footage without issues like frame dropping.
You can lower the gimbal all the way down to take a dronie shot, if you want.
This controller isn't one of the best around, but it does its job well.There aren't any fake buttons and everything does something.
The only disadvantage I could think of, would be the fact that the gimbal is controlled up and down by the press of two buttons, so the process is not too smooth.
The buttons are labeled as follows:
The controller is powered by 4 double A batteries and is by default set up to work in mode 2, with throttle on the left stick and pitch and roll on the right stick.
There is a fake screen in the middle and a set of 6 buttons on the side of it:
The flying process is a bit longer than a toy drone, but pretty standard for any other GPS drone.
Make sure to have at least 10 satelites connected, if not, the drone might not start, and it's probably going to fly imprecisely anyway.
There is a non-gps flying mode that allows you to fly the xk x1 at incredible speeds, probably something above 35km/h which can make it quite a fun drone to have for playing around.
The best place to buy it curently is banggood, where you can choose between 3 different packages (with different numbers of batteries included).
This is where I got it from and it should arrive within one to two weeks, depending on the shipping method.
