Hobbywing XRotor 20a Perfromance ESC (opto) only $10.99 USD
The Xrotor series ESC is a new and independent series hobbywing created based on the performance requirement on multi-rotor aircraft. The XRotor seriers speed controllers have significant improvements in throttle response, compatibility, usability over the existing series ESCs for aircrafts.
1.1 Special core program for multi-rotor controllers greatly improves throttle response.
1.2 Specially optimized software for excellent compatibility with disc-type motors.
1.3 All settings except the “Timing” are preset, making usage simple, highly intelligent and adaptive.
1.4 The twisted-pair design of the throttle signal cable effectively reduces the crosstalk produced in signal transmission and makes flight more stable.
1.5 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) .
1.6 Special drive chip has much better MOSFET driving effect than common driving circuit consisted of discrete components.
1.7 MOSFET with extra-low resistance brings high performance and great current endurance.
