RotorX RX1104 4000kv
Classic light weight micro motor
One of RotorX's earliest motors, the 1104 matches really well with a light 2" or 2.5" prop load. Giving a band of peak efficiency that covers in slightly lower loadings than other 11xx motors we've seen. Light 3" prop loads still fall under the 60% efficiency band, just a bit too far away from peak performance to really take advantage of it. Heavy 3" prop loads drop down into the 30 and 40% bands, not really taking best advantage of what the motor can offer.
Overall it performs very similar to the 1105b that came after, having efficiency that's relatively close overall and a very similar torque slope.
