A few months ago, I received a set of MEPS 2203.5 motors for review — designed for energy-efficient, long-range FPV drones. The MEPS AeroCore F722 Mini flight controller, weighing less than 15 grams, seemed like the perfect match to complete this lightweight setup. With a 20×20 mm mounting pattern for both the FC and ESC, it’s compatible with most FPV frames, making it a solid choice for compact and efficient builds.
The flight controller is essentially the brain of the drone. It processes signals from various sensors and interprets the pilot’s commands, translating them into precise instructions for the ESCs, which then convert those signals into motor outputs. In other words, it’s the component that keeps everything in sync — turning your stick movements into smooth, controlled flight.
With five UART ports, the AeroCore F722 Mini FC supports connecting various external devices such as a SmartPort receiver, TBS Nano RX, GPS module, or even an ultrasonic sensor.
Affordable Performance in a Compact Design – The AeroCore Flight Stack
Disclosure: I received this FPV stack for a product review collaboration with MEPS King. Although the products were offered free of charge, all opinions in this article remain my own, and the sponsor did not influence me.
MEPS has been a long-time partner of FirstQuadcopter. We reviewed their first set of motors back in May 2023, and I’ve liked their products ever since—they offer solid quality at a reasonable price. Many believe the company is somehow connected to T-Motor, one of the most reputable FPV parts manufacturers.
The MEPS AeroCore F722 Mini is the company’s third flight stack, designed for lightweight cruising FPV drones in the 3–5 inch range, where high power demand isn’t a priority. It’s optimized for smooth and efficient flights rather than aggressive racing or freestyle power bursts. Some racing beasts require ESCs rated at 60–70A, and using the 45A AeroCore ESC in such builds could easily push it beyond its limits—potentially burning it out on the very first full-throttle punch.
MEPS AeroCore F722 Mini at a Glance – Unboxing and First Impressions
Both boards come neatly packaged in identical black cardboard boxes with protective foam padding inside for added safety during shipping. The flight controller kit includes digital VTX cables (compatible with O3, O4, and OU systems) and two sets of rubber grommets — 4 mm and 8 mm — for flexible mounting options. The ESC package also includes two sets of rubber grommets, an XT60 battery lead, a 35V/470µF capacitor, and three FC interconnect cables. Both units feature a 20 × 20 mm mounting pattern with Ø 4 mm holes, making them ideal for 3–5″ FPV drones.
While both boards are quite compact, they feature reasonably sized solder pads with sufficient spacing to minimize the risk of mis-soldering or short circuits. The FC pads are clearly labeled; however, the lettering is rather small and not easily readable.

1. MEPS AeroCore F722 Mini flight controller
The F722 Mini FC measures 37 × 37 × 8mm and roughly weighs 5 grams. The board features a powerful STM32F7 processor, the reliable BMI2700 gyro, and a 96K PWM signal for smoother throttle response. This system delivers fast, stable, and precise control on every maneuver. It features a dual BEC system (5V 2A and 10V 2A) designed to power various external accessories such as a receiver (RX) or video transmitter (VTX) module. This built-in power regulation ensures clean, stable voltage delivery to sensitive components, improving overall system reliability and reducing the need for additional wiring or external regulators.
The board is equipped with a total of five UART ports, providing excellent flexibility for peripheral connections. Out of these, three UARTs are freely available for external modules such as GPS units, telemetry radios, receivers, or other add-ons. This generous number of serial interfaces allows pilots and builders to fully customize their setup without running into port limitations — a feature that sets this flight controller apart in its class. It also has dedicated solder tabs for a buzzer and an LED strip.
All solder pads, connectors, and the boot micro push-button are located on the front side of the PCB. The board features a USB Type-C port for configuration and firmware updates, an 8-pin ESC connector, and a 6-pin digital VTX connector (10 V, GND, TX1, RX1, GND, and R2-SBUS).
2. MEPS AeroCore 45A Mini ESC
Just like the flight controller, the ESC follows a clean and practical design philosophy. All solder pads — arranged in a 2×3 layout (one row on each side) for the motors, along with the positive and negative battery terminals — are conveniently located on the same side of the board, resulting in a neat, efficient, and builder-friendly assembly process.
It also features dedicated solder points for a low-ESR capacitor, helping to reduce electrical noise and voltage spikes during high-load operation. This thoughtful inclusion not only improves signal stability but also contributes to the overall durability and smooth performance of the power system.
The MEPS 45A Mini ESC runs on BLHeli_32 firmware and supports 3S to 6S LiPo batteries, delivering a peak current of up to 55A. It also features a built-in telemetry system and an integrated current sensor, providing real-time feedback for more precise power monitoring and tuning.
Pricing and Availability – Save More When Buying in a kit
At the manufacturer’s online shop, the MEPS AeroCore stack is priced at $28.90 (42% off) and the 45A ESC at $26.90 (52% off), totaling $55.80 if purchased separately. Choosing the complete flight stack kit costs $49.80, saving you $6 compared to buying the components individually.
