I have had this 3-battery, 1000m 5G 4K version of Eachine EX5 for a couple of months, but did not have much time to fly it. Here is a list of my findings:
CK
- EX5 is light with a weight less than 250g. As a result, no registration is required.
- EX5 DOES NOT have a micro SD card slots. This means videos and images must be streamed back to your phone. This proved to be very inconvenient.
- The app for EX5 is very poorly written because it can crash very frequently and unexpectedly. The most common situation to get a crash is entering the campus calibration. One brings the app and after some steps he app asks whether calibration was done. If for some reason you click NO, meaning you need a calibration, the app crashes bring you back to the home screen of your phone. Then, you have to reenter the app to finish the calibration process. Occasionally, the connection between the phone and the drone could be broken even though you can still fly the drone using the controller. Should this happen, the video streaming is disrupted and the video is not recorded. This can happen in an open environment within the distance of 100m.
- EX5 does not have a stabilized 1-axis (tilt) gimbal. Moreover, it is also difficult to fly the drone in a stable way. Therefore, videos shot with EX5 are not smooth.
- The build quality is not very good. the battery chamber cover was broken and flew away when my EX5 hit a tree branch, although the drone landed properly. Note that the EX5 has no obstacle avoidance mechanism.
- The 4K video shot with EX5 are not good. It looks like an interpolation from a low resolution image. Color rendition is washed out and inaccurate.
- The good point is that it costs much less than that of a Mavic Mini. I guess usually one can get a 1-battery version of EX5 slightly more than $100.
- It flies really well although not very stable and can be drifting in any possible direction. Therefore, don't expect that EX5 can hover just like a Mavic Mini.
- The Waypoint, Follow and Orbit features all work well. However, I have to complain about the Orbit feature. EX's manual fails to tell its user how to change the radius of the orbiting circle. If you tap the Orbit option at certain height, the drone seems to fly and point to north. Then, it starts circling at its minimal radius. How to increase or decrease this radius is still a mystery to me. Sometimes, the use of the right stick by pushing to the left or right seems to work. But, some other time, there is no effect.
- For Waypoint, a circle on the map is shown so that all points must be inside of the circle. Tis is perhaps good to beginners.
- Battery life is rather decent, but I do not have exact data. What I can say that a fully charge batter can last for close to 20 minutes or at least 16-18 minutes, which is good enough.
- The controllable range is claimed to be 1m. IMO, in the environment as shown in the clip below, 200m to 300m is the maximum. Either the control signal could become too weak or the WiFi connection with the phone for video streaming is lost. I will try to use a range extender. But, this could be a challenge because of the way of mounting the phone.
