Futaba 6EXAP_c8 6-Channel PCM 40MHz Airplane & Helicopter Transmitter System  [6EXAP_c8]

Product overview and controls

The Futaba 6EXAP_c8 is a six-channel R/C transmitter package designed for model airplanes and helicopters, supplied with an R136HP receiver and four S3003 servos. Its control layout and function set focus on in-field tuning, reliable channel mapping, and common flight features such as dual rates, flap control, retractable landing gear, and a trainer link for instructor-student setups.

This system is presented as an RC-scale accessory for model aircraft only. The description below summarizes the operator controls you will use during installation, setup, and flight trimming, and explains which receiver channels correspond to common model functions.

• Dual-rate switch: Toggles between two throw settings for aileron, elevator, and rudder, allowing a high-rate and low-rate configuration and switching exponential values when programmed.
• Flap control dial (Channel 6): Analog dial mapped to channel 6 for incremental flap positioning when flaps are installed.
• Aileron/elevator and throttle/rudder sticks: Primary control sticks for surfaces and throttle, with trim levers for fine neutral adjustments.
• Throttle-cut button: Provides an engine shutoff function by closing the throttle link when used on appropriate models and setups.
• Retractable gear switch (Channel 5): Dedicated switch for landing gear extension and retraction mapped to channel 5.
• Trainer switch: Enables trainer functions when connected to a secondary transmitter by trainer lead.
• Data input lever, MODE and SELECT keys: Navigate and set the transmitter’s parameters shown on the LCD.
• Charging jack and on-off switch: Battery charging port for the included charger and the main power control for the transmitter.
• Antenna: External radiating element that must be fully extended for normal operation to maintain signal range and reduce interference risk.

Use this transmitter and receiver set to map standard flight functions, establish dual-rate and exponential tuning, and manage auxiliary outputs such as flaps and landing gear; follow the included receiver and servo manuals for wiring and travel limits during installation.
