Currently, there are several types of FPV displays on the market but the most widespread are the 7″ FPV screens and FPV glasses. Frankly, I don’t think that gadgets like this GTeng T909 watch can compete with FPV goggles because they are not too practical. I think they can be used more for fun than for truly professional usage.
Although this kind of FPV gear is probably entirely new for most of us, Boscam has a very similar product for some time. I think that the GTeng T909 is a replica of the Boscam 200RC wearable FPV watch.
GTeng is a new brand in the drone market. They started with a couple of small quadcopters with innovative designs, and their “flagship” model is T901F, which can also be paired with this T909 FPV watch.
When I found out about this GTeng T909 FPV watch, I thought that it would be nice to have some of them in order to share my experiences with racing quadcopters with my friends. This doesn’t seem to be such a crazy idea as they are cheap; for $30, you can’t find any other usable FPV display.
Last month, I reviewed another 007 gadget, the watch-controlled FlyPro XEagle Sport quadcopter. My only disappointment was that the Xwath doesn’t offer a first-person view (FPV).
GTeng T909 review
This sample was offered for free by Gearbest to make an impartial review. Thanks again for your professional attitude.
The package was delivered quickly, and the only inconvenience was that the customs officer didn’t want to believe that the GTeng T909 costs only $ 34 (now it is even cheaper). He asked me to provide the site from where I purchased it. I think it is possible that he just wanted to order one :D.

GTeng T909 review – First impressions
Besides the FPV watch, I found a micro USB charging cable and a small instruction manual inside the neat cardboard box. On the bottom of the box, there are the full specs of the GTeng T909 and the list of receiving frequencies (Band/Ch).
Both design and build quality look quite good for its price range. Although many will consider it bulky, I liked the shape of this GTeng FPV watch. The black and green color combination makes it very hi-tech.
While the seller’s website says that it has a 2.6″ LCD screen, in actuality, it is a bit smaller one, measuring only 2″. On the right side of the GTeng T909 there are two buttons, the upper one allows to switch it On/Off, and the lower one to toggle among receiving frequencies. Short press to switch between channels (CH1 – CH8) and long press to switch between bands (A, B, E, and F ). On the bottom part of the wristwatch, there is an LED status bar that shows the selected channel.
On the left side of the T909 is located the 3db 5.8G antenna which can be folded neatly when not used. To obtain the best reception, I recommend setting the antenna’s position vertically.
Below the antenna is located the micro USB charging port. The integrated 300 mAh battery can be recharged through any USB socket using the included micro USB cable.
GTeng T909 FPV watch test
As the battery of the GTeng T909 was nearly empty before my testing, I had to recharge it. This process takes around 1 hour, the same as the working time.
Wearing the watch is pretty comfortable, except that it heated up a bit after longer usage and I sweated underneath.
Firstly, I tested it indoors using my RunCam Owl Plus camera and a 200mW 5.8G video TX. The signal was very stable, even through two brick walls. Unfortunately, the GTeng T909 does not allow to enhancement of the image quality through brightness and contrast adjustments.
I tested it outdoors with my Cheerson CX-35 FPV quad, but this GTeng T909 can be paired with any 5.8G FPV drone. I cannot lie that you can truly have a first-person view flight using this FPV gear. It is very hard to look at the wristwatch screen while using both hands to control the aircraft.
I thought that the 960 * 240 LCD is enough to display the smallest details, but unfortunately, after testing, it proved that I was wrong because the OSD telemetry values are hardly readable.
Although the manufacturer advertises this product with a receiving distance of about 60m, I read that someone managed to receive a clear video signal up to a distance of 400 meters. This huge difference is because the operating range of an FPV display varies greatly on the emission power of the TX module.
