  • MCU: STM32F722RET6 (216MHz).

  • Gyro: BMI270 / MPU6000 (Dual footprint design, usually BMI270).

  • Barometer: BMP280 (Ready for Altitude Hold/Rescue).

  • Blackbox: 16MB Onboard Flash.

  • Video: Dedicated connector for DJI Air Unit / Vista.

  • OSD: AT7456E (Analogue) + UART (Digital).

  • BEC: 5V/3A and 10V/3A (Clean power for VTX).

• ESC (60A BLHeli-S 4-in-1):

  • Continuous Current: 60A.

  • Burst Current: 80A (10 seconds).

  • Input Voltage: 3S - 6S LiPo.

  • Firmware: BLHeli-S (Supports DShot300/600, Bluejay flashable for RPM filtering)

  • Mounting: 30.5mm x 30.5mm (M3).

Compatibility & Platform Support

• DJI Digital FPV: Native. Includes a 10V BEC specifically to power the DJI Air Unit or Caddx Vista safely.

• Analogue FPV: Ready. Standard Video In/Out pads with OSD overlay.

• Firmware Target: SKYSTARSF722PRO.

Key Applications & Projects

• 7-Inch Long Range: The 60A ESC provides a safety margin for carrying large Li-Ion packs and fighting strong winds.

• High-KV Freestyle: If you run high-KV motors on 6S, you need the 80A burst rating of this ESC.

• Cinematic Lifter: Reliable enough for carrying GoPros and heavier cinema cameras.

Virtual Technician: Wiring & Safety ⚠️

• Capacitor: You MUST install the included capacitor (usually 35V 1000uF) at the battery pads. 60A current spikes can generate massive noise that will interfere with your video or reset the FC.

• Orientation: The USB port is located on the Side. Check the arrow on the board for the "Front" direction.

• Grommets: Use the included purple/black silicone grommets to soft-mount the stack. This reduces gyro noise significantly.

• Airflow: 60A generates heat. Ensure your frame has decent airflow over the ESC heatsink.

Accessories

• Included in the Package:

  • 1 x Skystars F722 HD Pro 3 FC

  • 1 x 60A BLHeli-S 4-in-1 ESC

  • 1 x XT60 Pigtail & Capacitor

  • 1 x Cable Set (DJI, FC-to-ESC)

  • 1 x Mounting Hardware (Screws & Grommets)

Frequently Asked Questions (FAQ)

• Is this stack compatible with the DJI O3 Air Unit?
  Yes, it features a dedicated 10V BEC and a 6-pin connector specifically designed for plug-and-play compatibility with DJI digital FPV systems.
• Can I use an analogue video transmitter with this stack?
  Yes, the flight controller has an onboard AT7456E OSD chip and standard Video In/Out pads for analogue camera and VTX setups.
• Does the flight controller support INAV for fixed-wing or autonomous flights?
  Yes, the SKYSTARSF722PRO target is supported by INAV, and the onboard BMP280 barometer provides the necessary altitude data.
• Will this stack fit in a 4-inch micro drone frame?
  Generally no, as this stack uses a 30.5mm × 30.5mm mounting pattern, which is standard for 5-inch to 7-inch frames, whereas 4-inch frames typically require 20x20mm stacks.
• Can I power this stack using an 8S LiPo battery?
  No, the ESC and flight controller voltage regulators are strictly rated for 3S to 6S LiPo voltages; using 8S will permanently damage the components.
• What is the maximum current the ESC can handle?
  It can handle 60A of continuous current per motor channel, with short 10-second bursts up to 80A.
• Is it safe to power a full-sized GoPro from the flight controller's 5V BEC?
  No, a full-sized action camera can draw more current than the 3A BEC can safely provide while also powering your receiver and GPS, which could cause a brownout.
• Where should I solder the included capacitor?
  You must solder the capacitor directly to the main battery input pads (VBAT and GND) on the ESC, matching the polarity strictly.
• How do I connect an ELRS or Crossfire receiver?
  Connect the receiver's TX to an available RX pad on the flight controller, and the receiver's RX to the corresponding TX pad (e.g., UART 2).
• Do I need to solder the ESC to the flight controller?
  No, the stack includes an 8-pin wiring harness that connects the ESC and flight controller directly without soldering.
• What is the correct firmware target for the flight controller in Betaflight?
  You must select the SKYSTARSF722PRO target when flashing new firmware via the Betaflight Configurator.
• What firmware comes pre-installed on the 60A ESC?
  The ESC comes pre-flashed with BLHeli-S firmware, which is highly reliable and easily upgradeable to Bluejay.
• Which DShot protocol should I select in Betaflight for this ESC?
  For BLHeli-S firmware, DShot300 or DShot600 are the recommended and fully supported motor protocols.
• Why is my computer not recognizing the flight controller when plugged in?
  Ensure you are using a high-quality data USB cable; if it still fails, you may need to run the ImpulseRC Driver Fixer tool to resolve Windows COM port issues.
• Why is my DJI O3 video cutting out when I punch the throttle?
  This usually indicates massive voltage spikes; ensure the included capacitor is securely soldered to the ESC battery pads to filter the power.
• Why are my motors twitching but not spinning smoothly?
  This is often caused by excessively long motor mounting screws touching the motor windings, or an incorrect DShot setting in Betaflight.
• Why am I not seeing the Betaflight OSD on my analogue goggles?
  Verify that your camera is wired to the Video IN pad and the VTX to the Video OUT pad, and check that the OSD toggle is active in the Betaflight Configuration tab.
