Sound drive controller SFR-1 from Beier-Electronic, finally together, what belongs together?

For the use in my Tamiya Arocs I decided for the new SFR-1. Above all, the place in the small hut of the Arocs was the decisive criterion.

In addition to the place I hoped for a device, instead of the previous variant with a speed controller (UFR) and a sound module (SFR), a simpler installation and a clearer configuration.

First, I took a look at the software. If you are familiar with the Drive-Teacher and the Sound-Teacher, you should not expect any surprises. The new SFR-1 Sound-Teacher combines the two "tools" in one. Thus, the configuration is much clearer, because you configure the vehicle in one place. If you configure it directly via K-USB-2, ie the data cable, all functions can be configured in one go. There is no need to switch back and forth between the two tools and devices until the desired configuration is achieved.
A closer look reveals that some configuration options that were previously "double" in the software have been simplified. For example, in the case of the return speed, you can only control via the gas curve and no longer in parallel via a radio button (reduction by 50%). All in all, the configuration feels smoother and in one piece.

The installation of the SFR-1 is easier than with his two "brothers". First, you notice that you save the wiring between the devices. The SFR-1 has two fixed prop channels for throttle and steering. The other connections can be used as required for Nautic, Servos or Proportional. If you use the terminals AKL-8, the LEDs can be connected directly. A power supply via a separate + cable is no longer necessary. The option of switching inputs via a separate switch is also eliminated and can be done directly via the proportional channels.
It is very convenient that the K-USB-2 can now be connected directly, without unplugging the IR diode!

The space required, especially in a narrow cab such as the Tamiya Mercedes-Benz Arocs, is significantly reduced. So fits in my example, the SFR-1 transversely between the cab floor and the frame. The engine is still a bit lower and even for the gear rod is still air.

In sum, my expectations were absolutely fulfilled. The sound control SFR-1 is simple and compact.
