  Tags: HOBBYWING XRotor Speed Control for Multicopters X-Rotor 

1 Special core program for multi-rotor controllers greatly improves throttle response.
2 Specially optimized software for excellent compatibility with disc-type motors.
3 All settings except the "Timing" are preset, making usage simple, highly intelligent and adaptive.
4 The twisted-pair design of the throttle signal cable effectively reduces the crosstalk produced in signal transmission and makes flight more stable. 
5 Compatible with various flight-control systems and supports a signal frequency of up to 621Hz (Note: all throttle signals over 500Hz are non-standard signals) .
6 Special drive chip has much better MOSFET driving effect than common driving circuit consisted of discrete components.

7 MOSFET with extra-low resistance brings high performance and great current endurance.
