Micro JST 1.25mm DT Release System
A complete DT (dethermaliser) release system for free flight models. Total system weight is just 5.0g, including the battery.
The low-current solenoid requires only 200mA to release the pin. It can hold up to ~200g of tension, making it suitable for most model sizes.
The included 100mAh battery (upgraded from 80mAh in previous versions) provides enough power for at least 10 days of use, or up to 30 days in idle mode.
The timer is configurable between 10–2500 seconds, allowing flexible dethermalisation timing. You can leave the battery installed throughout a full flight day or longer without issue.
⚠️ Note: Timer step size was 1 second in versions prior to Summer 2023. Newer versions increment in 10-second steps.
