E-Power Aria 35A BLHeli_32 Brushless ESC
The E-Power Aria 35A BLHeli_32 ESC is a compact, versatile brushless speed controller built for beetleweight combat robotics — capable as both a weapon ESC and a drive ESC. Running BLHeli_32 firmware on mature, well-understood Aria hardware, the Aria 35A is a stable, proven choice for builders already in the BLHeli_32 ecosystem or who prefer established firmware with a known behavior profile.
A note on BLHeli_32: it is no longer actively developed, but it is not broken. Thousands of combat robots have run BLHeli_32 successfully and continue to do so. If you are building a new robot or want the most future-proof option, the E-Power Aria 35A AM32 ESC runs identical hardware with AM32 — the open-source successor firmware. But if you know BLHeli_32, are replacing a known-good ESC, or simply prefer to stay with what you know, this is a solid choice.
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 — hardware that has been running weapon systems in beetleweight robots for years.
At 35A continuous on 3S-6S LiPo in a 32×16mm (1.25×0.64in) package weighing just 8g (0.3oz), the Aria 35A is one of the lightest and most compact options available for beetleweight builds. Forward-only by default, with bidirectional operation available via BLHeli_32 Suite for drive applications.
These ESCs work out of the box, but advanced users can configure their ESC parameters via a programmer like the Pearl Grey ESC Programmer USB-C. Using this ESC as a drive controller does require programming the ESC and setting the mode to bidirectional to allow reverse driving.
Need more current headroom for a heavier weapon system? The E-Power Aria 70A AM32 ESC is the next step up. Want AM32 firmware on the same hardware? The E-Power Aria 35A AM32 ESC is the one.

Frequently Asked Questions
Is BLHeli_32 still a good choice?
Yes — BLHeli_32 is mature, stable firmware that has powered thousands of combat robots successfully. It is no longer actively developed, which means no new features, but it is not broken. If you know the BLHeli_32 ecosystem or are replacing a known-good ESC, this is a solid choice. For new builds where long-term firmware support matters, the AM32 version is worth considering.
What is the difference between this and the AM32 version?
Identical hardware — the only difference is firmware. The AM32 version runs open-source firmware with active community development. This version runs BLHeli_32, which is stable but no longer in development. Both are configured via their respective software suites and both support the same protocol list.
This says forward only — can I enable reverse?
Yes — forward-only is the default configuration, which is correct for most weapon applications. Bidirectional operation can be enabled through the BLHeli_32 Suite using a Pearl Grey ESC Programmer USB-C.
Do I need to program this ESC before use?
No — the Aria 35A works out of the box for brushless weapon motors in forward-only mode. Programming is optional and only needed if you want to change firmware settings such as direction, braking, PWM frequency, or throttle response. If you do want to configure it, the Pearl Grey ESC Programmer USB-C is compatible with BLHeli_32.
Does this ESC include a BEC?
No — the Aria 35A does not include a Battery Eliminator Circuit. In a typical combat robot wiring setup, receiver power is supplied by your drive ESCs or a dedicated BEC. This is standard for high-current weapon ESCs and keeps the design simple and lightweight.
What is the difference between the 35A and 70A versions?
The 35A is smaller and lighter — ideal for drive systems and lighter weapon motors in beetleweight builds. The Aria 70A provides more current headroom for heavier weapon systems where sustained high current draw is expected. Note that the 70A is AM32 only — there is no BLHeli_32 variant at the 70A rating.
