ARMATTAN DSHOT 30 AMPS BLHELI_S ESC/BB2 US$13.50
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.
Excellent filtering with over a dozen low ESR capacitors.
The icing on the cake is the sticker you see in the picture. It's not a sticker. It's a 0.3 gram heatsink made of aluminium that is first anodized black and then laser engraved. This provides exceptional protection to the ESC against the dreaded blade stikes. Note that the heatsinks are made, by hand, in remote regions of the Himalayas.
These ESCs run smooth and they are reliable. No highway robbery, either. Good bang for your buck.
