Futaba 6EXAP_c8 6-Channel PCM 40MHz Transmitter for Airplanes and Helicopters  [6EXAP_c8]

Transmitter overview and controls

The Futaba 6EXAP_c8 is a six-channel R/C transmitter package intended for model airplanes and helicopters, supplied with an R136HP receiver and four S3003 servos. The layout and feature set prioritize quick in-field trimming, straightforward channel mapping, and familiar flight options like dual rates, flap control, retractable gear and a trainer link for instructor-student use.

This set is described as an RC-scale accessory for model aircraft use only. The summary below explains the operator controls you will use during installation, setup, and flight trimming, and it details which receiver channels are commonly used for standard model functions.

• Dual-rate switch: Selects between two servo throw presets for aileron, elevator and rudder, allowing reduced or full response and switching associated exponential values when programmed.
• Flap control dial (Channel 6): An analog dial mapped to channel 6 for stepped or incremental flap positioning when flaps are installed.
• Aileron/elevator and throttle/rudder sticks: Primary sticks for surface and throttle control, each with trim levers for accurate neutral adjustments.
• Throttle-cut button: Provides an engine shutoff function by interrupting the throttle link when used on models equipped for this feature.
• Retractable gear switch (Channel 5): A dedicated switch mapped to channel 5 for gear extension and retraction.
• Trainer switch: Activates trainer functions when linked to a secondary transmitter via the trainer lead.
• Data input lever, MODE and SELECT keys: Used to navigate menus and change transmitter parameters displayed on the LCD.
• Charging jack and on-off switch: The battery charging port accepts the included charger and the on-off switch controls main power.
• Antenna: External radiating element that must be fully extended during normal operation to preserve signal range and minimise interference risk.

Use this Futaba transmitter and receiver set to assign standard flight functions, set dual-rate and exponential values, and operate auxiliaries such as flaps and landing gear; always follow the included receiver and servo manuals for wiring and travel-limit setup during installation.
