100A Per Channel for 13–15 Inch Heavy Lift
The 100A 4-in-1 is built for 13–15 inch heavy-lift, cinematic, and industrial multirotors requiring high sustained current. With 100A continuous and 120A burst per channel on 4-8S, it drives large 4320-4720 motors with ease — ideal for professional camera rigs, survey platforms, and cargo drones.
10kg Payload Capacity
Rated for platforms up to 10kg total weight, the 120A is the go-to choice for heavy commercial multirotors — industrial inspection, agricultural spraying, and medium-payload logistics. The 30.5×30.5mm/M4 mounting fits standard large-format flight controllers.
120MHz Processor + Bidirectional DSHOT
The 120MHz AT32F421 ensures bidirectional DSHOT300/600 runs flawlessly even at high motor RPM on large props, providing accurate RPM telemetry for Betaflight filtering. On 12-14 inch frames with high rotational inertia, clean RPM data is essential for stable, jitter-free flight.
8AWG Leads & Dual Capacitors
8AWG power leads with an Amass XT90 plug minimize resistance at 120A loads, while dual 2200µF capacitors suppress voltage ripple during aggressive throttle transitions. The ESC stays at 27g and 57×54×6.5mm — surprisingly compact for its current rating.
AM32 Firmware, Tunable for Industrial Use
Open-source AM32 with web configuration allows precise tuning for industrial motor/prop combinations, including custom startup profiles for heavy-lift applications. Full over-temperature, low-voltage, and signal-loss protection ensure reliability during long commercial missions.
