It’s perfectly sunny and dry outside, but I’m a lazy ass and want to fly indoors. And that’s why, the FX797T is my best friend today!
If you aren’t aware, the FX797T is a $40 piece of kit that can put FPV on virtually any quadcopter. It weighs 4.5g, and comes with its own FPV transmitter. Let’s take a look at the specifications:
- Input: 2.5-5V (works on a 1S/3.7V LiPo)
- FPV transmission frequency: 5.8GHz (5 bands; 40 channels, with Raceband: 5658-5917MHz)
- FPV output: 25mW
- Camera: 600TVL
- FOV: 120-degree
- Antenna dimensions: 20mm X 25mm
- Antenna type: 3 lobe right hand circular polarized
- Weight: 4.5g
And here is the frequency chart:

|Frequency Band E||5705||5685||5665||5645||5885||5905||5925||5945|
|Frequency Band F||5740||5760||5780||5800||5820||5840||5860||5880|
|Frequency Band R||5658||5695||5732||5769||5806||5843||5880||5917|
Inside the box, you get the camera + VTX combo itself, English user’s manual plus a LiPo splitter cable that allows you to use one 3.7V 1S LiPo to power your quad as well as the FX797T.
I got hold of one today (from Banggood.com), to use with my micro quads. Have a look at the unboxing video first:
The range of this micro FPV camera + VTX combo is pretty impressive, and better than what I expected. You can easily go over 100 meters outdoors, but the purpose of this gadget is mainly indoor flights. And with that, you can expect a range of let’s say, one to two walls.
Without any obstructions, and with a cloverleaf antenna on your receiver, you can easily get over 300 meters of clean FPV footage.
I plan to use the FX797T with my XK X100 quadcopter (see photo above). An article talking about that will be up very soon!
The FX797T also happens to be the preferred camera of choice (along with the FX798T) amongst Tiny Whoop pilots. Expect a tonne of ducted quadcopters from China in the coming weeks, mostly in the $15-20 range. A couple of them have already popped up, in the Eachine E010 and the Nihui NH010.
The point of concern for me is only the antenna, which seems susceptible to breakage. It may be a good idea to fly with low rates in the beginning. 😉
In the coming weeks, I plan to use the FX797T with a range of different micro quads, including the XK X100, Eachine H8 Mini, and more. Stay tuned!
