43 products
A 30x30 4-in-1 ESC puts four motor controllers on one board with 30.5×30.5mm mounting holes — the standard stack size on 5-inch and larger FPV frames. This page collects every 4-in-1 ESC in our range with that mount, from 45A boards for freestyle quads to 100A 8S boards for cinelifters and 10-inch builds. Choose by current rating and cell count first, then firmware, and check that the connector matches your flight controller.
How to choose a 30x30 4-in-1 ESC
- Current: 45–60A per motor covers a 5-inch on 6S. 7-inch builds are comfortable at 55–65A. 8 to 10-inch and cinelifter builds want 70–100A.
- Voltage: most boards are 3–6S. For 8S, pick a board rated for it — a 6S ESC will not survive an 8S pack.
- Firmware: BLHeli_S boards run Bluejay for RPM filtering. BLHeli_32 is no longer developed, so newer 32-bit boards ship with open-source AM32. All work with Betaflight.
- Cooling and build: a metal heat sink or an aluminium case helps on heavy builds where the stack sits out of the airflow.
- Current sensor and telemetry: check the board has them if you rely on mAh-used in the OSD.

Compatibility
The ESC connects to the flight controller with an 8-pin cable carrying battery voltage, ground, current, telemetry and four motor signals. The pin order differs between brands: compare both pinout diagrams and re-pin the cable if needed before powering up. Fit a low-ESR capacitor across the battery pads; most boards include one. Any 30.5×30.5mm flight controller stacks on top.
Frequently asked questions
- What amp rating do I need for a 5-inch 6S quad?
- 45A to 60A per motor is plenty for freestyle. Racing builds and heavier 5-inch quads with large motors benefit from 60A or more for headroom.
- Can I run 8S on any 4-in-1 ESC?
- No. Only boards rated 3–8S or 4–8S take an 8S pack. Running 8S through a 6S board destroys it, usually on the first plug-in.
- BLHeli_S, BLHeli_32 or AM32?
- All three fly well. BLHeli_S boards with Bluejay firmware are the budget choice, BLHeli_32 boards still work but get no updates, and AM32 is the open-source 32-bit firmware on current designs.
