Features: 1BEC output of ESC, boost and step?down exist simultaneously, is suitable for any standard receiver. 2The motor is super light weight. Whether you use 1S or 2S lithium, BEC output is 5V/3A. 3Brushless ESC that can meet the requirements of high?speed motor. 4When ordinary ESC encounters high?speed motor, it will slow down or protect if the throttle cannot reaches 100%. However, this ESC will not have this problem. 5Special designed for fixed wing aircraft, wonderful and practical accessory. Condition: 100% Brand New Item Type: ESC Material: Electronic Components Continuous Current 7A, maximum 9A (10 seconds) Built-in BEC, 5V voltage output to the receiver, when 1S power supply, voltage BEC boost to 5V, when 2S power supply, voltage BEC step-down to 5V, suitable for all standard receivers, ESC provides 3A BEC output, to meet 1-4 small steering servo to use. The ESC program is an optimized high-speed program, meet the low speed motor at the same time, more suitable for high speed motor, such as 1220-12000kV within 2S, 1104-4500KV within 2S, or 0705-15000KV. Suitable for: Fixed wing aircraft Package Included: 1 x ESC
