Good practices
We have compiled a list of all of practices which have been tried and tested in countless environments and
situations by the TBS crew and other experienced FPV pilots.
Follow these simple rules, even if rumors on the internet suggest otherwise, and you will have success in
FPV.
●
Start with the bare essentials and add equipment one step at a time, after each new equipment
was added to proper range- and stress tests.
●
Do not fly with a video system that is capable of outperforming your R/C system in terms of range.
●
Do not fly with a R/C frequency higher than the video frequency (e.g. 2.4GHz R/C, 900MHz video).
●
Monitor the vitals of your plane (R/C link and battery). Flying with a digital R/C link without RSSI is
dangerous.
●
Do not use 2.4GHz R/C unless you fly well within its range limits, in noise-free environments and
always within LOS. Since this is most likely never the case, it is recommended to not use 2.4GHz
R/C systems for longer range FPV.
●
Do not fly at the limits of video, if you see noise in your picture, turn around and buy a higher-gain
receiver antenna before going out further.
●
Shielded wires or twisted cables only, anything else picks up RF noise and can cause problems.
●
When using powerful R/C transmitters, make sure your groundstation equipment is properly
shielded.
●
Adding Return-To-Home (RTH) to an unreliable system does not increase the chances of getting
your plane back. Work on making your system reliable without RTH first, then add RTH as an
additional safety measure if you must.
●
Avoid powering the VTx directly from battery, step-up or step-down the voltage and provide a
constant level of power to your VTx. Make sure your VTx runs until your battery dies.
●
Do not power your camera directly unless it works along the complete voltage range of your
battery. Step-up or step-down the voltage and provide a constant level of power to your camera.
Make sure your camera runs until your battery dies.
●
A single battery system is safer than using two dedicated batteries for R/C and FPV. Two batteries
in parallel even further mitigate sources of failure.
●
For maximum video range and “law compatibility”, use 2.4GHz video with high-gain antennas.
●
When flying with R/C buddies that fly on 2.4GHz, or when flying in cities, it is perfectly possible to
use 2.4GHz video provided you stick to the channels that do not lie in their band (CH5 to CH8 for
Lawmate systems, available from TBS).
●
Do not use diversity video receivers as a replacement for pointing your antennas, diversity should
be used to mitigate polarization issues.
