E-Power Aria 70A AM32 Brushless ESC The E-Power Aria 70A AM32 ESC is a high-current weapon speed controller built for the demands of competitive beetleweight combat robotics. Running on AM32 — the open-source firmware successor to BLHeli_32 — the Aria 70A delivers smoother low-speed control, better torque response, and active community development that BLHeli_32, now discontinued, can no longer offer. For builders who want a capable, future-proof weapon ESC on proven hardware, this is the one. If you previously ran the FlashHobby Aria 70A, this is your replacement — same platform, better firmware. E-Power has been manufacturing brushless ESCs and RC electronics since 2007, with CE, ROHS, and FCC certification. The Aria series represents their combat-ready line — the same platform that has been running weapon systems in beetleweight robots for years, now upgraded to AM32 firmware. The hardware is mature and well-understood; the firmware is actively maintained. At 70A continuous on 3S-6S LiPo in a 21×42mm (0.83×1.65in) package weighing 18g (0.6oz), the Aria 70A fits where weight and space are at a premium — which is always in a 3lb robot. The aluminum heatsink cover and multilayer thickened PCB keep resistance low and thermals manageable under sustained weapon loads. Forward-only by default, with bidirectional operation available via AM32 Configurator for builders who need it. Running a lighter weapon or drive system? The E-Power Aria 35A AM32 ESC and E-Power Aria 35A BLHeli_32 ESC are worth a look.
