Ryze Tech Tello Quadrocopter in field test: Battery life, flight characteristics, range and video quality check


Average 0/5
The Ryze drone is light and handy and should convince with a lot of functions in the air. The copter is not from DJI, as wrongly assumed, but carries only many parts that DJI and Intel have made.

Nevertheless, we would like to know whether the Tech Tello beginner drone flies as well as a large drone from the industry leader DJI – the quality of the components should definitely be up to the task!

Tech Tello scope of delivery

The package of the drone doesn’t promise too much and offers a very lavish set of accessories.

The Tello can be controlled via mobile phone using the Tello app or via a controller, which is not included and has to be purchased separately. This controller is compatible with the drone.


The controller lies very well in the hand and makes a very high-quality impression. The same applies to the body of the copter: nothing wobbles, the battery sits firmly and the propellers can be screwed on and off very easily.

The weight of the drone is less than 250g, so you don’t need a license plate to fly the Tello drone.

Range and behaviour in the air

The range of the drone is limited to 100m according to the manufacturer. We could reach 65m in our range test. After that the picture transmission signal was partly interrupted and a safe flight became impossible.

Furthermore you can climb up to 10m into the air. If you go even higher, you risk that the signal breaks down. But that’s enough and it’s a lot of fun.

A full battery charge will keep the drone in the air under full load for about 11 to 12 minutes. This value is absolutely top in view of the low price and clearly superior to some competing models such as the Parrot Mambo (7 to 8min) or the Parrot Airbourne (8min).

Unfortunately I could not try flying with virtual reality glasses yet, because I lent my Parrot Bepop 2 (this set included FPV glasses) to a buddy. The app is simple and clearly arranged and reminds a bit of the DJI-GO app.

The take-off and landing procedure could not be easier for beginners. Just press the start button in the app and the drone takes off on its own.

The Flight-Positioning-Sysrtem really does a great job and the quadrocopter is standing in the air as if it were chiseled in. For a mini drone without GPS or the Russian satellite system Glonass, the “stay on the spot” characteristics are absolutely top.

Slight gusts of wind are no problem for the Tech Tello, but stronger winds should be avoided as you can quickly lose control of the remote control or the mobile phone. However, this is no wonder with such a lightweight.

The DJI Tello immediately implements all flight commands without delay, which I give it on the way by mobile phone. The image transmission also shows no latency or dropouts, as is the case with some models in this price class.

A very cool feature are the flips that can be performed by the Tello. To do this, you just have to switch to stunt mode on the phone screen and then point on the screen with a finger and show the copter in which direction the flip should be executed.

Please note that there must be enough space available, as the quadrocopter needs 1 second after the stunt is over to return to its starting position and navigate independently.

This works absolutely problem-free, but the drone sometimes drifts a little bit to the side, so there should be no obstacles in the way.

The 360° function worked very well in the test. The drone then automatically starts a video recording and flies around an object completely independently without you having to do anything.

The camera has to be aligned accordingly beforehand, as the position of the drone camera cannot be changed while orbiting (as is the case with Mavic Air or Mavic Pro in point-of-interest flight mode).

A further flight mode of the Tello Quadrocopter is the up and down flight where a video recording can be produced. I haven’t found any real use for this feature in practice (which is not bad at all!)

Overall I am very satisfied with the flight characteristics and pleasantly surprised how much precision and sensitivity the drone brings to this price class – hats off!

Photo and video recordings in check

The photo quality is definitely good for a copter in the lower price range and is clearly superior to comparable drones in this price range. The photos are sharp, detailed and the colours are rich in contrast under good lighting conditions.

When it is dark outside, the pictures don’t look very special. The ISO value cannot be adjusted in the app. Nevertheless, the photos are really good, in my opinion. You can see some sample photos here

The videos in HD format (1280×720 pixels) are also usable. Of course the recordings are not world class and not enough to make professional movies, but the next birthday party can be documented from the air.


Although a gimbal is missing, the video recordings are relatively stable. Nevertheless, the videos are of course not comparable to those of a Mavic Air or Mavic Pro.

If you are looking for a drone that can record similar videos, but in Ultra HD (4k), you should take a closer look at the UPAir 4k.

My conclusion about the Ryze Tech Tello drone

I find this very reasonably priced drone very successful. This is partly due to the very high quality hardware, which comes not least from DJI and Intel, and partly to the very simple intuitive flight characteristics.

Within the sector beginner drone this is my personal test winner. All factors are just right and the quality is, as usual from DJI, outstanding.

Quality for the small purse, more is really not possible in this segment and at this price.
