Feature 1High Performance: Use powerful and high performance microprocessor, allowing users to customize functions according to their needs, showcasing its intelligent features. Unique circuit design, strong anti interference. 2150A Brushless ESC: Start mode can be set. Throttle response fast, and it has a very smooth speed control linearity. Compatible with fixed wing aircraft and helicopters. 3Multiple Protection Functions: The low voltage protection threshold can be set. Input voltage abnormal protection or low voltage cutoff protection, over thermal protection and throttle signal loss protection, make the ESC more reliable. 4High Power Safety Performance: The motor will not immediately start regardless of the throttle stick position. The ESC status can be determined through alarms. 5Powerful: Support voice mode, voice broadcast programming options, and exceptions such as low voltage and signal loss for a more intuitive understanding of the current status of ESC.Item Type: RC Drone Brushless ESCMaterial: Plastic, Aluminum AlloyWeight: Approx. 293g / 10.3ozContinuous Current: 150APeak Current: 170ACompatible Battery Cells: 5-12SProduct Size: Approx. 115x48x28mm / 4.5x1.9x1.1in (Excluding Cables and Capacitors) .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 xRC Drone Brushless ESC1 x Instruction Manual
