A little gadget for our sound speed controllers of the SFR-series and the sound module USM-RC-3.

With the Bluetooth module BTC-1, the modules can be controlled via Bluetooth using the Android app “SFR-1 Controller”.

Using the app, all available functions (additional sounds, WAV player, lights, servos, etc.) of the module can be controlled. With the SFR it is also possible to direct the drive (throttle and steering). A parallel operation next to a standard RC transmitter is also no problem.

The range is, due to the low transmission power of smartphones and tablets, between 10 and 30 meters! The control via Bluetooth, is therefore only suitable for models that do not exceed this distance to the transmitter!
