Description

From the listing uploaded by “appupdater”.

With the app "SFR-1 Controller", the sound speedcontroller SFR-1, SFR-1-D and SFR-1-HL can be controlled via Bluetooth. This requires the Bluetooth module BTC-1, which can be ordered in our online shop: https://www.beier-electronic.de/modellbau/produkte/btc-1/btc-1.php With the app, the model can be driven (throttle and steering) and all available functions (additional sounds, WAV player, lights, servos, etc.) of the SFR-1 series can be controlled. Also a parallel operation of a standard RC transmitter and Bluetooth control is possible at the same time. Functions: • Throttle and steering via position sensor of the Android device • Throttle and steering via touch control in the directional pad • 20 freely assignable buttons • 30 freely assignable buttons, if you do not want to drive via the app. Like a graphical multiswitch module • Buttons can be labeled arbitrarily • Buttons with or without memory mode • Volume adjustment • Model memory for any number of models
