Description

The SFR-1-D is an allround module and combines the sound module USM-RC-3 and the double speed controller UFR-1230-D in one unit.

It comes with a large light control unit, four servo outputs, two additional mini speed controller, extra outputs for smoke generator, Xenon flash and IR battle-unit (Torro/Taigen/Heng-Long).

With various setting options the SFR-1-D can be easily adjusted to all model requirements and driving behaviors. For an easy start we have about 100 ready to use sound projects and 700 sound files for various model types.

The Software Sound-Teacher SFR-1-D is only for Windows,
with an emulator like WineBottler is is also possible to use the Sound-Teacher with a Mac or other operating systems.

Sound functions:

For an authentic sound of the model, sounds can be selected for following areas:

• Driving and engine sounds for one motor (speed-dependent)
• Additional sounds (e.g. horns, hydraulic and compressed air noises)
• Random sounds (e.g. squeaking, animal and ambient sounds)

Driving functions:

One brushed and bell-armature motors (DC) can be controlled smooth and realistic with the SFR-1-D. An ideal driving behavior can be achieved through a large number of settings.

The speed controller on the SFR-1-D has following characteristics:

• Different mixer types
• Different brake functions (with hand- and emergency brake)
• Adjustable load regulation
• Adjustable mass inertia
• Steering inertia (with adjustable steering ankle limits)
• Adjustment of throttle curve for different driving behaviors

Light functions:

To realize different light effects, the SFR-1-D has 16 switching outputs to connect LEDs, lamps and other consumers. Light functions, such as low beam, rear light, brake light, indicator lights, warning lights, flickering lights, etc. can be easily implemented and controlled.

All light functions can be activated or deactivated manually with a proportional channel, a nautic/multiswitche modules, the Android Bluetooth App "SFR-1-D Controller" or automatically by sounds and movements.

Servo movements:

With four additional servo outputs, movements can be synchronized to the played sound.
All SFR-1-D functions can be activated or deactivated manually by proportional channel, nautic/multiswitche modules, the Android Bluetooth App "SFR-1-D Controller" or automatically by sounds and movements.
