Details

The T-Motor setup comes pre-fitted with a two-blade propeller for straightforward installation on multirotor builds.

The T-Motor propeller dimension diagram provides key measurements for checking fit and clearance during setup.

The performance curves compare thrust (g) against RPM, torque (N·m), current (A), efficiency (g/W), power (W), and Fff (%).

The A12L-18S modular propulsion system comes with a parts bag including mounting plate, hardware, hex tool, and strap for installation.
