About Xflow and makers
Every successful model is the result of thousands of launches, countless hours of testing, and years of competition experience. Xflow was developed following exactly the same philosophy.
It was not designed to replace the Encanto. Instead, it builds on everything that made the Encanto successful while taking its flight performance to the next level.
Throughout several competition seasons, we tested different setups, compared the model against the best competitors in a wide range of weather conditions, and carefully analyzed its behavior during every phase of flight. The result is a model designed not to compromise, but to give the pilot greater confidence and more precise control.
During the development of Xflow, we focused on three key objectives:
- More precise and stable thermalling, especially in small and weak lift.
- Higher tow release altitude.
- A wider setup range for both calm and windy conditions.
The wing, airfoil, planform, and wing area had already proven their performance on the Encanto, so they remained unchanged. Our development efforts focused primarily on the tail section.
A redesigned rudder with increased effectiveness, together with the relocated horizontal stabilizer, provides noticeably improved handling. Xflow turns more naturally in tight circles, holds its line more accurately in thermals, and loses significantly less altitude during downwind transitions. Positioning the horizontal stabilizer in cleaner airflow also improves control authority while reducing aerodynamic interference from the wing wake.
The improvements are equally noticeable during towing. Xflow remains stable and well aligned behind the towline almost until release, allowing consistently higher release altitudes and giving the pilot a greater opportunity to locate lift.
Landing performance also received considerable attention. The perforated airbrakes provide smooth deceleration with only a minimal increase in sink rate. Combined with high-angle-of-attack flight (Harrier), Xflow allows exceptionally slow, stable, and highly accurate landings, even in demanding conditions.
Xflow is not a model that flies by itself. It is a model that allows skilled pilots to get the very best from their abilities. It offers a wide usable speed range, a calm and predictable flight character, and precise control throughout every phase of flight.
We believe these qualities will allow pilots to focus on what matters most—making the right decisions in the air and achieving better competition results.
Karol Chyba - developer, manufacturer, seller of Xflow.
I was 11 years old, when I met first time with RC models. Since I was little, I looked up at the clouds and at the airplanes. For my skills, I went on high school section aircraft mechanic. After school, I went through many other professions, but mechanical engineering and RC model making stayed with me until today. I was active pilot in cat. F5J. When I met first time with cat. RES/F3L, I knew, that will be new chalenge for me. I started tinkering with the first MOANA model. Then came other generations of models and finally I approached Jan to see if he would continue with me in further development of models in this beautiful category. Me and Jan complement each other very well and I think that we have done a good job with our latest Xflow model, which will also satisfy other pilots who will fly with it. My achievements in F3L Eurotour: 5 times podium place in competitions and 3 times in the TOP 10 overall ranking league.

I was former pilot category F3J. I flew F3J for 19 years (2000-2019). The greatest success is F3J World champion individual senior category from 2014. I finished two times on second place on World Championships 2012 and 2016. When I finished with category F3J, I could not find correct category. In 2021 I start cooperate with Karol on Vaiana Sport and I found great category RES/F3L. Two times winner of F3L Eurotour league (2023,2024). My goals in F3L and F5L category are support juniors and find great model with high-tech performance.
