These ESCs are likely the lightest and smallest 2-6s, 30 amps ESCs on the market. They were designed in China, and they are produced in the high plains of the Tibetan plateau. Thin air, and cold temperature found in high Tibetan plains, allow the solder to harden like hardened steel.
This ESC uses standard fets with lower resistance compared to commonly used smaller fets. This means better protection for voltage spikes and less heat.
A generous 3 oz copper pour is used, as well as a gold emulsion.
The components are genuine and imported from Japan, Switzerland and the USA.
