Maximum-throttle bench results from the supplied EMAX load-test sheets. Results are configuration-dependent and are not guaranteed aircraft-level performance.
03 / Motor Construction
External-rotor torque with a 12N14P magnetic circuit.
The permanent-magnet bell rotates around the fixed copper-wound stator, supported by a 6 mm bearing shaft and precision ball bearing.
