The Flash Hobby ARIA Slim 40A ESC is a compact, high-performance speed controller designed for FPV drones running 3–6S LiPo. Built around a 32-bit STM32F051 MCU, it delivers fast, precise throttle response and smooth motor control, now running open-source AM32 firmware for flexible configuration and ongoing support.
The ESC features a low-profile, slim form factor designed specifically for mounting on drone arms, keeping builds lightweight, tidy, and improving airflow for better cooling — ideal for racing and freestyle setups where space and weight matter.
Integrated telemetry support and current sensing provide useful real-time data for OSD monitoring, while the onboard RGB LED allows for custom visual feedback.
Optimised for modern digital protocols, the ARIA ESC supports DShot (150–1200) along with legacy PWM options, ensuring compatibility across a wide range of flight controllers and setups. Efficient MOSFETs with added heatsinking improve thermal performance under load, making it suitable for demanding applications.

Questions and answers of the customers
There are no questions yet. Be the first to ask a question about this product.
Here at Flying Tech we have a wide choice of electronic speed controllers (ESCs).
There are two main types of ESCs: 4-in-1 ESCs and single ESCs. A 4-in-1 ESC integrates four individual ESCs onto a single circuit board, each controlling a separate motor. A single ESC controls only one motor.
This 4-in-1 ESC is a more popular choice for racing quads, while single motor aircraft such as fixed wings would use a single ESC. Single ESCs are still used by some drone racers though, as after a crash or a burnt up ESC, they only have to replace one, not an entire 4-in-1 or stack which is a lot more costly. Single ESCs are also available which much greater current ratings (80amp +) so they are also used by power hungry multi-rotors, for example X-Class racing quads, professional camera flying “Cinelifters”.
When using individual ESCs, they typically need to be connected to a single power distribution board (PDB) or an “AIO flight controller” (a type of flight controller with integrated PDB) for power supply.
