Futaba T6K-V3S Transmitter

Manufacturer: Futaba Corporation
Model: T6K-V3S

Basic model with enhanced glider functionality

The T6K V3S uses the 2.4GHz two-way communication system, T-FHSS AIR, and has enhanced glider functionality in addition to the functionality of airplanes, helicopters, and multicopters, making it a high-performance radio control system that, despite being a basic model, allows for the pursuit of infinite possibilities.

Features

  • 8-channel airborne radio control: Compatible with airplanes, helicopters, gliders, and multicopters.
  • Telemetry function: The aircraft is equipped with the two-way communication system T-FHSS Air. By combining the voltage of the receiver battery installed in the aircraft and various optional telemetry sensors, various aircraft information such as power battery voltage, altitude, speed, and temperature can be displayed on the transmitter.
  • In addition, you can monitor numerical values ​​by voice using earphones, and a vibrator can be used to warn of low voltage and other issues.
  • Backlit LCD: A large, backlit graphic LCD panel is used. Graphs such as EXP curves can be displayed, making setup easy.
     Seven languages ​​are supported, with Japanese displayed in katakana.
  • Built-in antenna: The handle has a clean design.
  • Intuitive settings with jog keys and buttons

  • Volume ch: Can be assigned as an auxiliary ch.
  • Battery Requirement: Requires four AA batteries (rechargeable batteries are also available separately).

Functions & Specifications

Common (Airplane / Helicopter / Glider / Multicopter)

  • 30 model memories: Name each model freely (up to 8 characters), and organize your fleet with ease.
  • Wing & tail types: Choose from 5 airplane wings, 6 glider wings, and 2 tail options to match your airframe.
  • Swash types (heli): Select one of 6 swashplate layouts (H-1 / HR3 / H-3 / HE3 / HN3 / H-2) for clean CCPM geometry.
  • Program mixing (4 channels): Build four independent mixes—3 linear and 1 five-point curve—so you tailor control exactly.
  • D/R (Dual Rate): Tune aileron, elevator, and rudder throw for precision or agility.
  • EXP (Exponential): Shape response on aileron, elevator, throttle (except in heli mode), and rudder.
  • Fail-safe (all channels): Predefine safe positions across the board for signal-loss events.
  • Battery fail-safe (T-FHSS Air): Set the trigger voltage by pack type to protect your model when voltage sags.
  • Trim step: Adjust how much each trim click changes the setting.
  • Trim type: Pick Normal or ATL (for throttle only), and—for other trims—make trim strongest near center and taper toward the ends.
  • Stick alarm: Play a warning when the throttle hits a specified position.
  • Battery warnings (beep/vibrate): Get low-battery alerts and set the threshold to match your chemistry.
  • Core setup tools: Set end points, digital trim, sub-trim, reverse, and use servo display / servo test for verification.
  • AUX CH: Assign CH5–CH8 to your preferred switches or knobs.
  • Dual timers: Store two timers per model so you don’t re-enter values when you switch.
  • S.BUS servo programming: Edit S.BUS / S.BUS2 parameters right from the radio.
  • Trainer: Choose a training style—limit channels or assist only with counter-rudder—and coach with confidence.
  • I/O & service ports: Use the trainer connector, a 3.5 mm stereo earphone jack, and the S.IF port to configure S.BUS servos and telemetry sensors.
  • User name: Register up to 8 characters for quick identification.
  • Model management: Copy models and transfer data wirelessly with Model Transformer.
  • Screen adjustments: Set contrast and backlight for any lighting.
  • RF formats (2.4 GHz): Run T-FHSS Air or S-FHSS (set this in the Model Select screen). Pair with receivers like R3008SB / R3204SB for T-FHSS Air, or R2001SB for S-FHSS. (Telemetry doesn’t operate in S-FHSS mode; see the receiver compatibility list for details.)

Airplane-Only

  • Throttle cut and idle down for safer ground handling.
  • Throttle curve for smooth power delivery.
  • Gyro (1 axis): Adjust sensitivity and mode from the radio (Panasonic-compatible).
  • Aileron differential and V-tail for coordinated handling.
  • Camber and air brake logic for approach control.
  • Elevator→Flap and Flap→Elevator mixes for pitch-stable flap use.
  • Elevon for delta and tailless wings.

Helicopter-Only

  • Conditions: Set idle-up and throttle hold for confident autorotation and maneuvers.
  • Throttle cut for safe shutdowns.
  • Trim offset: Store separate trims for hover and flight, and add delay when you switch for smooth transitions.
  • Gyro (1 axis): Adjust gain from the transmitter (Panasonic-compatible).
  • Swash AFR and Swash Mixing to refine cyclic response.
  • Throttle & pitch curves to shape power and lift across the stick.
  • Pitch→Rudder to keep the tail locked during collective changes.
  • Hovering throttle / hovering pitch for stable station-keeping.
  • Governor mix: Set headspeed from the radio (works with Futaba governors and gyros with built-in governors).

Glider-Only

  • Condition select to swap quickly between launch, cruise, thermal, and speed.
  • Motor switch for clean electric-glider arming.
  • Gyro (1 axis): Tune gain from the transmitter (Panasonic-compatible).
  • Aileron differential and V-tail for efficient soaring.
  • Butterfly (crow) for steep, controlled descents.
  • Trim Mix: Move AIL/ELE/FLP/RUD trims to preset positions with a switch.
  • Elevator→Camber and Camber mixes for precise wing shaping.
  • Aileron→Camber to couple roll input with wing camber for better turns.

Multicopter-Only

  • Flight Mode selection for different mission profiles.
  • Center alarm: Play a tone at a chosen throttle position to aid camera ops or arming.
  • Throttle curve and throttle delay for cinematic control.
  • Gyro (1 axis): Since the FC handles primary stabilization, use this channel for camera-stabilizer tuning (Panasonic-compatible).
