Details

The T-Motor AM850 is designed for 84–89 inch 3D RC planes (550–65cc class).

The X-shaped mounting plate uses a matching bolt pattern for quick, non-destructive replacement during installation.

T-Motor’s calibrated power curve concept is presented for smoother throttle response and controlled 3D maneuvers.
AM850’s zero-latency and precise tracking helps keep control inputs responsive for precise flying.

The setup pairs a carbon fiber AMZ 23×10 propeller with a T-Motor-style motor and AMZ-216A ESC for a clean, high-power drive system.

Lock-nut mounting, a 4.5mm adjustable blade seat, and color-coded plugs help make motor and ESC installation quicker and cleaner.

The T-Motor AM850 KV195 motor documentation includes key dimensions, electrical specs, and a contents list for installation planning.
