- Lightweight and compact: 4.4 grams and dimensions of 19.0 x 30.0 x 9.0 mm (W x L x H). This ultra-small size helps fit in tight airframes while preserving payload capacity and flight dynamics. - Broad 2.4 GHz compatibility for small electric models: Suitable for a wide range from mini profile foam airframes to 400 meter class helicopters, providing flexible application across many small aircraft. - Advanced Digital Spread Modulation 2 technology: Delivers enhanced signal reliability and stable control by using the Digital Spread Modulation 2 method, improving resistance to interference in common flying environments. - Strict compatibility with DS2 systems: Designed to work only with Digital Spread Modulation 2 aircraft radio and module systems, ensuring proper operation and performance when used with compatible equipment. - Use scenarios: - In a micro foam profile plane that requires a light, space-efficient 2.4 GHz receiver to maintain flight agility. - In a small electric helicopter where low weight and reliable signal are critical for steady handling at typical range. - In a DS2 radio setup for compact park flyer or trainer aircraft, leveraging the DS2 modulation for consistent link quality.
