The SFR-1 is a multifunctional module which combines the sound module USM-RC-2 and the speed controller UFR-1230 in one unit. It comes with a large light control unit, three servo outputs and an port for the light modules LM-BT-16-4 and LM-IR-16-4 to transmit light signals to a trailer.

The SFR-1 is suitable for all types of RC standard transmitter. With the various setting options the SFR-1 can be easily adjusted to all model requirements and driving behaviours. For an easy start we have more than 140 ready to use sound projects and 700 sound files for various model types. Of course, own recordings can be used, as well.

All settings are programmed with the software SFR-1 Sound-Teacher and saved on a micro SD card. The programm is only for Windows, however 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. An ideal driving behavior can be achieved through a large number of settings.

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

• Cruise control functions
• 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 has 16 switching outputs to connect LEDs, lamps, smoke generators 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 or with nautic/multiswitche modules and automatically by sounds and movements.

The SFR-1 has a special port to connect the IR transmitter for the light module LM-IR-16-4 or the bluetooth transmitter for the light module LM-BT-16-4.

Servo movements:

With two additional servo outputs, various additional movements can be realised and synchronised to a sound.

The SFR-1 unit comes with:

• 1x Speaker cable
• 1 x Volume/standby cable
• 1x 40cm ribbon cable with IDC plug
• 2x 30cm receiver patch cables
• 1x 32GB micro SD card with standard SD card adapter.
