The Remote DT B1 is a compact and versatile dethermaliser/timer designed for small free-flight models. Suitable for both competition and general hobby use, it is ideal where a lightweight and economical DT system is preferred. It also supports the conversion of rubber-powered models to electric flight.
The Transmitter:
The transmitter is approximately the size of a matchbox and uses a single-button interface to control the receiver. Each unit broadcasts a unique digital code, which the receiver memorises during binding. One transmitter can control any number of receivers. It is powered by a CR2032 coin cell battery.
The Receiver:
The receiver supports 9 different modes, including Servo, Band Burner, and E20 electric motor control. It is optimised for 1S LiPo power and accepts input voltages from 3–9V.
⚠️ Important: The output voltage is unregulated and will match the input voltage. Ensure all connected components—such as servos, motors, or the band burner board—are compatible with this range.
