Overview

The T-Motor AM20 F3P-A is a brushless outrunner motor designed for F3P indoor precision flight and indoor aircraft setups. It is offered in two KV options: 1500KV (optimized for 2S) and 1900KV (optimized for 1S).

Key Features

  • High-precision build for smooth F3P-style slow flight.
  • Curved rare-earth magnets, ultra-tight air gaps, and high-tolerance assembly (as stated).
  • Integrated propsaver with 5.5mm flange, plus 7mm and 8mm adapter bushings (as stated).
  • Dual carbon mounting plates for versatile installation (includes a larger carbon fiber cross to suit different mounting sizes).
  • Good throttle linear (as stated).
  • Silver wire note: due to different batches, there may be differences in the color of the enabled silver wire.
