he FX798T Micro FPV Camera & 5.8GHz 40CH 25mW VTX is extremely small and could be installed on almost anything. The unit is ultra-lightweight, so it is easy to place on any aircraft without affecting the COG. Most multi-rotors wouldn’t even notice it was there. This Camera / VTX combo is a popular choice for adding FPV to the Blade Inductrix micro quadcopter.

It’s easy to install and operate with one push button to change channels and bands. Just plug into a little 1S Lipoly battery or onto your 5V rail and you are ready to go.

It has excellent video and low latency for such a small package. The combo also includes a splitter and a circular polarized 5.8G tuned antenna for the best video signal.

DSLR (and GoPro) camera accessories are extremely expensive. Even more so for rigs. And yet rigs are 
some of the products that can be 3D printed more efficiently. The biggest challenge – as is often the 
case -is designing them but through open source sharing, it may be enough for one person to begin and 
let everyone contribute to provide the community with several affordable designs.
