AM780 Power System for 76"–83" 3D Airplanes | 50–55cc Gas Replacement | 20kg Thrust

The Ultimate 50-55CC Gas-to-Electric Conversion for 3D Aerobatics

The T-Motor AM780 Power Combo is a high-voltage electric power system purpose-built for 76"-83" (50-55CC class) 3D aerobatic airplanes and scale UAVs. Engineered as a direct, non-destructive replacement for traditional 50cc gas engines, the system includes the AM780 160KV motor, AM156A HV ESC, and an AMZ 22x10 carbon fiber propeller.

Running on a 10S-12S LiPo configuration, the AM780 generates up to 4656W of power and 20kg of instant continuous thrust. Its custom throttle curve—calibrated by world-class 3D pilots—delivers zero-latency throttle tracking and linear control required for low-altitude hover, pop-tops, and aggressive XA maneuvers. With a shared mounting footprint for gas engine firewall patterns, it offers RC pilots a quiet, clean, and highly responsive alternative to gas powerplants.

Key Selling Points

• 50-55CC Gas Engine Equivalent: Direct electric conversion for 76"-83" (1.9m–2.1m) 3D aerobatic aircraft and scale UAVs.

• Instant 20kg Continuous Thrust: Paired with the AMZ 22x10 carbon fiber propeller, delivering instantaneous power response with zero throttling latency.

• Plug-and-Play Non-Destructive Mounting: Features matching bolt patterns for popular gas engines (e.g., DLE55) with included multi-spec mounting bases and standoff spacers.

• High-Voltage 10-12S Power Architecture: AM780 160KV motor capable of 4656W peak output and 92A peak current, optimized by top international 3D pilots for linear throttle resolution.

• Pro-Grade Thermal Dissipation: 180°C high-temperature rated magnets, 1000V  coil insulation withstand test, and integrated ESC cooling fan for continuous high-load maneuvers.
