James Hohensee Crowned 2026 US National F3K Champion, Secures Third Straight US Team Berth
Congratulations to James Hohensee on being crowned the 2026 US National F3K Champion—his second US National Champion title—while also securing his place on the US F3K Team for the third consecutive year. The 2026 championship, held at the AMA NATS, was a combined event that also served as the US Team Select for the 2027 F3K World Championship in Bulgaria. James earned his spot on a strong three-pilot US team alongside Oleg Golovidov and Frank Dumas III.

Precision That Performs at the Highest Level
During the championship, James equipped his competition aircraft with KST A06 LV V6.0 servos throughout.
Designed specifically for lightweight F3K competition gliders, the A06 LV V6.0 delivers the responsiveness and reliability that world-class pilots depend on:
-
Ultra-lightweight construction — just 6.5–7g
-
Outstanding centering accuracy — 2µs dead band for precise positioning
-
Fast and precise response — 0.11 sec/60° at 4.2V
-
Proven reliability — hardened steel gears and dual ball bearings for demanding F3K competitions
Whether performing high-energy launches or making delicate thermal corrections, the A06 LV V6.0 provides the precision that competitive F3K pilots trust under pressure.

Team KST on the International Stage
The 2026 NATS brought together many of the world's best F3K pilots across a challenging weekend of rapidly changing weather—rain, wind, dead calm, and heat all in a single day. We are proud to see Team KST pilots competing at this level. Congratulations to:
-
James Hohensee — 2026 US National F3K Champion; US F3K Team member (3rd consecutive year)
-
Eitan Rotbart — 9th place at the 2026 NATS F3K
-
Mengchen Li — 6th place at the 2026 NATS F3K
Thank you all for representing Team KST with professionalism, passion, and outstanding sportsmanship.

Why F3K Pilots Choose KST A06 LV V6.0 Servos
F3K (Radio Control Hand-Launch Glider) is one of the most demanding disciplines in RC soaring. Pilots launch their gliders by discus throw, then search for thermals and complete precision-duration tasks—all within tight time windows. Every gram, every millisecond, and every degree of centering accuracy matters.
That is why serious F3K and DLG pilots choose the KST A06 LV V6.0:
-
Lightweight enough for the smallest, most efficient competition airframes
-
Fast enough for instant thermal corrections and precision landing approaches
-
Precise enough to hold trim with confidence in turbulent air
-
Reliable enough to perform round after round at national and world championship level
Congratulations to All Team KST Pilots
Every competition is an opportunity to push the limits of precision, innovation, and performance. We sincerely congratulate all Team KST pilots for their excellent results and thank every pilot who chooses KST servos to compete at the highest level. We look forward to many more successful seasons together—and to cheering on the US F3K Team in Bulgaria in 2027.

Frequently Asked Questions
What is F3K?
F3K is the FAI international class for Radio Control Hand-Launch Gliders (also called Discus-Launch Gliders, or DLGs). Pilots launch gliders by discus throw and compete in precision-duration tasks, searching for lift (thermals) to maximize flight time and landing accuracy.
Did James Hohensee make the US F3K Team?
Yes. James Hohensee earned a place on the US F3K Team for the 2027 F3K World Championship in Bulgaria—his third consecutive year on the team. He joins teammates Oleg Golovidov and Frank Dumas III.
What servo does James Hohensee use in F3K competitions?
James Hohensee uses the KST A06 LV V6.0 micro coreless digital servo in his competition glider.
How much does the KST A06 LV V6.0 servo weigh?
The KST A06 LV V6.0 weighs approximately 6.5–7g, making it ideal for lightweight F3K and DLG competition airframes.
What voltage does the KST A06 LV V6.0 servo require?
The A06 LV V6.0 operates on DC 3.5–4.2V, optimized for a single-cell (1S) LiPo battery.
