Mo-Sys L20 takes to the Slopes
RTS puts Mo-Sys L20 through its paces at the Alpine Ski World Cup 2026. From high-speed pans to precise tracking in a fast-paced, snow-packed environment, the L20 proved exactly what it was designed for on one of live sports’ most demanding stages.
We’re delighted to have supported RTS in capturing every turn, jump and finish-line moment for audiences at home.
Read their feedback on our L20:
"I had the opportunity to test the L20 head during one of the FIS Alpine Ski World Cup races in Crans-Montana. This technology allowed us to operate remotely in locations that would otherwise be inaccessible for our crews, while delivering the extremely fast movements required to capture the true speed and intensity of the skiers."
Aurélien Vallotton, TV Director
"During the Alpine Ski World Cup, I had the opportunity to operate a camera fitted with the L20 motorised head, mounted on a stabilised system similar to a Ronin. It was the first time I’d used this precise system, although I’d already worked with somewhat similar setups before, but generally less technologically advanced and less precise in terms of adjustments.
It took me about an hour to understand the various settings and really get to grips with the system. What particularly struck me about the L20 is the level of precision it allows. You can make very fine adjustments to the various axes, such as tilt or pan, as well as the sensitivity of the movements. This allows you to tailor the head’s behaviour very precisely to your operating style and the type of footage you wish to produce.
There’s inevitably a bit of a learning curve at first. Operating it requires a certain amount of coordination, and there’s a rather technical, almost “gamer”-like aspect to the way you control the camera. But you quickly get the hang of it. Once the coordination between your gaze, your brain and the movements of your hands falls into place, everything becomes much more instinctive.
Coming from the world of FPV drones, I personally really enjoyed the experience. It offers that same highly immersive flying sensation, where precise control and synchronised movements are essential to achieve exactly the framing or movement you want.
I think this system has real potential. I’m not yet sure to what extent this type of technology is already being used in other competitions, such as the Ski World Cups, but it clearly opens up some interesting possibilities. Once you’ve got the settings right and know the movement cues, you can track a subject or an action with great precision, whether it’s in motion, tracking or managing the zoom.
In any case, the experience was very positive for me. And if I had to do it again, I’d do it without hesitation tomorrow."
Louis Coubés, operator of the L20 system during the World Cup
"A big thank you to Mo-Sys, who allowed us to test their L20 head. Their helpfulness and responsiveness were particularly appreciated. We installed the device on the same platform as an 8-metre crane, and despite the very heavy workload at an event of this scale, the ease of setting up the head meant we were up and running very quickly. Their RF control kit proved extremely practical. I was impressed by the speed and precision of the L20 head."
Guy Sandmeyer, Head of video production, In charge of slope during Alpine Ski Cup Montana 2026
"We began our collaboration with Mo-Sys through the StarTracker system, which we are currently deploying in our new studios. This gave us an excellent opportunity to test another field of expertise from Mo-Sys, the L20 camera heads, which offer truly state-of-the-art control and movement capabilities. Our operator highlighted how easy the system was to install and how intuitive the control interface felt, which significantly streamlined the evaluation process. Throughout the entire collaboration, the Mo-Sys team was fully committed and supportive. It was a real pleasure to work with such a professional and dedicated group."
