Leptron RDASS™ HD
Unmanned Quadcopter

The Rapidly Deployed Aerial Surveillance System (RDASS) HD by Leptron UAS, Inc. is a professional-grade vertical takeoff and landing platform engineered for stability, versatility, and remote data collection. The RDASS HD is developed with a unique aerodynamic design and advanced electronics that maintain incredible aircraft stability even in unpredictable wind conditions. Enhanced safety features such as intelligent fault detection- automatically prompts the RDASS HD to safely return home and land in the event of lost communications, low battery, or when commanded by the pilot.

The RDASS camera mounting system accepts Leptron stabilized or fixed gimbal configurations. Each gimbal is perfectly balanced to eliminate excessive power draw caused by in-air leveling corrections. Additionally, the RDASS HD can be equipped with navigation LEDs, remote video viewing, and a ground control station. With dozens of user defined system configurations available, the RDASS HD is an ideal choice for industry professionals.
