The drones with FPV camera for WiFi are not exactly to my liking as a rule. When the real time image of the camera of a drone reaches you via WiFi, it usually gives many problems in the lower price ranges of this hobby (interference, exaggerated delay in the image, very blurry ...) but with this JJRC H20W I have to Recognize that I have been impressed with what it offers. Let's go with the review.
We can not be confused: the JJRC H20W is not a normal JJRC H20 with FPV camera. They are drones that aesthetically have made them very similar but that in the rest they do not resemble at all: in size, flight style, control .. Nothing. We are facing a drone much closer to the range of mini drones (a bigger palm of a hand) whose references are the Hubsan X4 h107, Syma X11, JJRC H6C ... things like that.
On the other hand, and leaving the FPV and recording the camera for the end, we have to emphasize greatly its great resistance to the wind. We are facing a drone that knows how to fight wind gusts of 20km / h, which for a drone of this type has a lot of merit. It is a pleasure to see how JJRC strives every day to make drones that can with this type of unforeseen, since it is of the most important in this range to improve these points.
As for normal flight, we are facing a really stable drone if you like but also with a very fast one. We can get to complete circuits fairly fast compared to the price and strength of this drone, which leaves hallucinated many times. It may be that its higher speed mode is very unstable and especially fast in the beginning, but once mastered ... will be one of the greatest pleasures in flying this drone.
Regarding the range, make it clear that it is not a drone to move it beyond 20 or 30 meters, since we can not control it with the view and it starts to give dots of sporadic signal loss. It is not a very bad thing, but I would not take it beyond those distances, which is when the eye starts not to distinguish well the nose of the drone's ass). About its autonomy, we are before the 6 minutes or 7 long, depending on how you fly and such, but how we can exchange their batteries ... I think it is something very interesting and positive for this drone.
On your FPV, say that we are not before one that goes by the frequency of 5.8 gHz (which is the most normal and recommended to watch the video in real time) but if it perfectly achieves its goal: to be able to control the drone from the screen . We may sometimes find ourselves in greater delays, it may, but that is not the norm, seeing in real time a great caldiad of video that will allow us to recognize the terrain perfectly.
Another theme is how you record the drone's camera to see it in your house. A very bad video quality that will hardly serve to make small assemblies or things like that. Low definition, very moved, deformations and too saturated colors ... Come on, let alone the format, which is not exactly too friendly.
In short, this is a very interesting drone and if you are convinced by the concepts I mentioned in the article you should go head over it, since the price, to this day, is not too bad.
Additionally, if you need to purchase some rc drone parts, you can search via Banggood website, which is one of the wholesale platform to provide affordable prices, such as camera keychain, f645 helicopter camera, etc.
