The Flycolor X-Cross HV3 120A (5–12S) is a single-motor ESC from the Chinese manufacturer Flycolor for X-Class FPV and larger multicopters. It drives one motor, works on 5 to 12S and runs BLHeli_32 firmware.
The continuous current is 120 A and the peak current 150 A for 10 s (retailer figure). 5 to 12S corresponds to 21 V to 50.4 V fully charged. The 132 g includes the connecting leads; the board alone weighs correspondingly less. BLHeli_32 is a 32-bit firmware with DShot up to 1200 and Bidirectional DShot; it is closed and, according to retailers, has not been developed further since 2024. Existing functions stay usable, new ones do not arrive.
Frame and law: the aircraft decides the classification. X-Class FPV sits above 250 g, larger multicopters reach classes C2 and C3. On 12S each ampere-hour of battery brings about 44.4 Wh, and a pack from roughly 3.6 Ah is above the 160 Wh IATA limit for air transport.
For selection, the flight controller and the configuration tool should fit the firmware. Anyone who values continuing firmware maintenance also compares controllers with open firmware such as AM32. As for wear, 120 A strains the solder joints and lead roots; the heavy leads carry vibration into the board. Discolouration and loose leads are warning signs.

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.
