This motor from Brother Hobby was specifically designed for light weight 4inch and 5inch machines. The “returner” series of motors are known for high quality, HIGH output power, and light weight.

The 2850KV is suggested for 4inch props. Compared to a 1407 motor these have quite a bit more torque allowing you to use heavy pitch blades. Even heavy pitch tri blades will be no problem!

On the Superlight Norris 5inch – With the higher 2850KV option on 5inch props you will have higher top speeds, but more loading on your system. We have tested the Norris on the 2850KV version with 5040 Tri Props with fantastic results, however you need to keep AUW (before lipo) to no more than 220g, and run no larger than a 1300mah lipo. The 2850KV option will run a bit on the warm side. Light weight is KEY.
