Upgrade your Mark4 APEX XL FPV drone with the Readytosky F7 F722 / F4 F405 Flight Controller and 60A 4-in-1 BLHeli_S ESC stack — a high-performance flight control solution designed for 5–10 inch racing and freestyle frames. Built for precision, speed, and reliability, this stack is perfect for RC FPV enthusiasts looking to maximize control, power, and stability on every flight.
The F4/F405 or F7/F722 flight controllers feature STM32 MCU processors, integrated Betaflight SPI OSD, and MicroSD black box recording for accurate flight data capture. Equipped with dual BEC outputs, multiple UARTs, and support for SBUS, CRSF, IBUS, and XBUS receivers, these controllers provide seamless connectivity for cameras, receivers, and peripherals.
Paired with the 60A 4-in-1 BLHeli_S ESC, which supports DShot600, Oneshot125, Multishot, and PWM signals, the stack ensures smooth motor response and consistent power delivery across 3–6S LiPo setups. EMI shielding and on-board filter capacitors stabilize voltage and protect sensitive components, giving you high-performance reliability even under aggressive flying conditions.
Whether you’re building a 5-inch, 7-inch, 8-inch, 9-inch, or 10-inch FPV frame, this stack is designed for easy installation (30.5×30.5mm mounting) and shock column support, making it the ideal upgrade for racing and freestyle FPV drones.
