Futaba 6EXAP_c8 6-Channel 40MHz Radio System with R136HP and 4xS3003  [6EXAP_c8]

Product summary and control layout

The Futaba 6EXAP_c8 bundle includes a six-channel transmitter, an R136HP receiver and four S3003 servos, crafted for both model airplanes and rotorcraft. Controls and switches are arranged so pilots can perform real-time trimming, assign dual rates, operate flaps and manage retractable landing gear during pre-flight and flight adjustments.

This description treats the kit as an R/C accessory for model aircraft. Below is a concise guide to the operator controls used during mounting, initial setup and flight trimming, plus which receiver channels typically map to common model functions.

• Dual-rate switch: Select between reduced and full travel presets for aileron, elevator and rudder; exponential changes follow the selected preset if programmed.
• Flap control dial (Channel 6): Provides an analog input on channel 6 for gradual flap deployment when installed on the model.
• Aileron/elevator and throttle/rudder sticks: Core sticks control surfaces and engine/throttle, each fitted with trim levers for precise neutral adjustment.
• Throttle-cut button: Shuts off engine power by isolating the throttle path on compatible setups, used as a safety or emergency stop.
• Retractable gear switch (Channel 5): A dedicated switch mapped to channel 5 for raising and lowering retractable landing gear.
• Trainer switch: Enables trainer operation when connected to a second transmitter via the trainer lead.
• Data input lever, MODE and SELECT keys: Menu navigation controls for setting transmitter options shown on the LCD screen.
• Charging jack and on-off switch: Charge port for the supplied charger and the main power switch for the transmitter.
• Antenna: External antenna that needs to be fully extended during normal operation to preserve range and limit interference.

Employ this Futaba package to configure standard flight channels, tune dual-rate and expo settings, and control auxiliary functions like flaps and gear; consult the receiver and servo manuals for correct wiring and travel-limit adjustments when installing.
