The SFR-1-HL at a glance:
DescriptionThe SFR-1-HL is a multifunction all-rounder module, designed for the tanks of Torro / Taigen and Heng Long (up to 4th generation). The module replaces the (simple) original control unit for a much better sound and driving behaviour.
All connectors are compatible with the tank wires. One exception is the 4th generation the Heng Long RX-18. This generation requires an adapter plug to control the turret.
Thanks to various setting options the SFR-1-HL can be easily adjusted to all model requirements and driving behaviors. For an easy start we have more than 30 ready to use sound projects for different types of tanks. Own recordings can also be used.
The Software Sound-Teacher SFR-1-HL 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.
To control the tank, a "standard" RC remote control with a "standard" RC receiver is required for the SFR-1-HL. The tank's original transmitter cannot be used in combination with the SFR-1-HL! It is also possible to control the tank with the Android app SFR-1 Controller and the Bluetooth module BTC-1.
