Let me start by giving you my credentials: I grew up in the r/c aviation hobby with over 30 years experience flying planes, helis, and multirotors LOS (line of sight). Just recently I've taken the plunge into FPV (first person view I have been following the Tiny Whoop craze and these little micro cameras with VTX intrigued me.



The camera was tucked tightly in its foam insert with the lens cap on and attached battery lead wrapped around the antenna's post. Underneath the first foam insert was another foam insert that had the battery lead splitter tucked into a cavity. Under the last foam insert was the instruction manual. Inspection of the camera and antenna showed no signs damage or wear. A perfectly boxed item.


Using the Camera:

Power on the camera is as simple as plugging the battery in. Once the battery is connected two LEDS light up on the back. The LEDS indicate the selected band and channel within the band. I don't have goggles yet, but I have a monitor that came with my LY-250 quadcopter. This monitor is hard coded to an unknown channel. Fortunately the FX797T allows for changing the frequency and I was able to get the monitor to pick up the signal by switching the camera to the channel referred to as F7. Once the signal was locked in I was shocked/surprised at the clarity and sharpness of the picture. I was expecting some blurriness/less sharp image. Boy was I wrong. Holding the camera I panned around my room at differing speeds to get a feel of what it'll look like. With the initial test/trial passed and working, it was time to figure out how to mount the camera and play with FPV.


For my first true FPV experience I decided to attach the camera to my Keliwow Charge-4 R/C 4WD ATV. I attempted to use a big block of soft foam to get it high enough over the front of the ATV velcroed down (double sided tape on the velcro to the camera and ATV). Statically the image was perfect and what I was expecting. However, once I started driving around my backyard, the camera was bouncing around way too much. The foam and velcro was not enough to keep it stabilized. So I kept my speeds low and drove around FPV for about 12 minutes (running the ATV hard at full throttle yields drive times around 6-8 minutes). I had a huge grin on my face driving FPV. The only time I had any issues with video signal was when I would get about 20 feet away from me with a big pile of wood and myself being between the monitor with video receiver and the ATV. If I stopped the ATV in this scenario I'd lose signal completely, but if it was just a quick drive through I only saw a few lines of static but the picture was still usable. I used the same lipo for both drives (close to 25 minutes of driving) and the lipo was close to a storage charge afterwards. Without an OSD showing battery voltage, keep an eye on your time if you are using its own lipo for power. After both drives I noticed the side of the camera felt warm/hot to the touch. So be sure no to have it sit still/wind blocked of it or it may burn up.



This is a fantastic and great micro FPV camera. Being 25mW a HAM license is not required in the US, so it's legal to plug and play. The NTSC format is crystal clear and the signal strength is great for the small FPV ships. I will be making a more modular mount to allow this camera to be mounted on many different r/c vehicles (quadcopters, airplanes, and surface vehicles). Switching the 5.8GHz frequency is easy and the LEDs on the back of the camera telling you the frequency it's on is fantastic/perfect. The camera performs pretty well in sun and shade, transitioning between can fake the camera out a little, but it'll settle down and give a perfect picture again very quickly.


Should you buy this camera to FPV? Yes!

Can I use this for Tiny Whoop? YES!

Will the antenna break? Probably if it's hit and banged enough times.


So, if you want to get into FPV without breaking the bank do yourself a favor and get the FX797T camera and at least one 1S lipo used on ultra micro aircraft from Horizon Hobby. I definitely see myself making high use of this little camera.
