The T-MOTOR T-HOBBY Mini F60A 4in1 (20x20) is a compact 4-in-1 ESC from the Chinese maker T-MOTOR under the T-HOBBY brand for small FPV quadcopters. The format is 20 × 20 mm and the firmware AM32.
The 60 A comes from the type designation F60A, i.e. it names the current class per channel; what current a board of this size delivers continuously depends on airflow, installation and battery lead. The voltage window runs from 3S to 8S, i.e. up to 33.6 V fully charged. AM32 is open firmware that can also supply motor speed for RPM filters; telemetry is available. The board sits in the 20 mm grid, which marks small builds with little room for cooling.
Frame and law: for builds of this size the 250 g limit matters: below 250 g take-off mass an aircraft falls in the range of class C0, above that operator registration and a proof of competence are due. On 8S an ampere-hour of battery is about 30 Wh, and the IATA limit of 100 Wh lies at about 3.3 Ah.
For selection: four channels on 20 × 20 mm give up heat only through a small area, so do not count on four times 60 A but on the current draw of the motors with reserve. One failed channel affects the whole board. After crashes check the solder pads at the battery connection, the capacitors and the MOSFETs for burn marks or cracks.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Ask about parts availability for this build year — the running costs hang on it.
