TomCat Skylord Advance 120A Speed Controller ESC 5-8V/10A BEC

TomCat Skylord Advanced 120A is an electronic speed controller (ESC) for controlling the motor speed and is applicable for 500~550 class helicopters (propeller: 470~575mm) and large duct airplanes. This ESC, whose continuous current is 120A, supports multiple flight modes, including Fixed-wing, Helicopter (Linear Throttle), Helicopter (Elf Governor), and Helicopter (Store Governor). It also supports multiple protections and can be adjusted parameters by a 3-in-1 program card, which is convenient for the user.

Systematic Design in Heat Dissipation

The top of the ESC has a special casing with a slot for conducting heat, which could enlarge the radiating area. Two fixing holes for the fan, the user could install the fan or not according to their own needs.

Internal silicone pad for conducting heat clings to the MOS power elements, which could dissipate the heat to the maximum. As for the bottom of the ESC casing, multiple ventilation holes are designed for better usage.

Multiple programmable items and adjustable sensitivity of speed governing make the flight as you wish

In a separate programming port for ESC programming or parameter setting, the user could check the minimum voltage, max temperature, and max current, then program the ESC. As for the motor speed governing, the user could adjust the governor parameters to achieve precise control and perfect flight to one's own needs.

Independent high voltage BEC

New switch-mode independent BEC with adjustable output voltage ranges from 5V to 8V and continuous/peak current of 10A/25A, which could drive the motors to achieve the perfect flight. Independent BEC module design will keep the normal output and reduce the risks of crash when the MOSFET board of the ESC is burnt.

Multiple functions and settings, safer and more reliable

The user could assign the Start-up time of the ESC in StoGov and ElfGov modes to make the motor start extremely smooth and could effectively avoid tail-drift issues. Also, in this mode, the user could program the "AR Time" and "Restart Accel" to break the autorotation and restart up, reducing the possibility of a crash resulting from incorrect operation.
