With powerful and high-performance MCU processor, users can set and use functions according to their own needs, which fully reflects the intelligent characteristics of our products' advantages Support unlimited speed of brushless motor Careful circuit design, anti-interference , high-precision, ultra-low-dropout three-terminal regulator () for MCU, work more stable The starting mode can be set, the throttle response speed is fast, and it has a very stable speed linearity, which is compatible with fixed-wing aircraft and helicopters. Built-in SBEC/UBEC, with high load power with servo Possess a variety of protection functions: abnormal input voltage protection / low battery protection / overheat protection / throttle signal loss delay stop Good power-on performance: When the power is turned on, the motor not start the motor immediately regardless of the remote control throttle lever in any position Over-temperature protection: When the temperature reaches 120 when the controller is working, the power output automatically reduce the power, and the power output automatically recover when the temperature is below 120 Compatible with all remote control operation settings and support programming card settings High cost performance, high performance and low price, it is a good choice for amateurs and competitions Color: As Shown Material: ABS Package Contents: 1 set * HW30A speed controller Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
