Notes from the Team-Legit Tech Department:
These cost-effective 40A ESCs are great options for basic airplanes up to 4S. Lightweight and compact, these ESCs include linear BECs which are more than adequate for servo pairs in flying wings. If you have a large number of digital servos or need 6S power, an ESC with a switching BEC will be a better choice.
