If you want 803 authority but want the extra power of a 2S 65mm build, these are the motors for you.
At 803 12000kv, these motors are excellent for 2S builds. You'll feel a lot more transient response than 802 motors, meaning that the motors get up to speed considerably faster. This is what most people simply call "power." You'll feel a new level of freedom when you're freestyling, pulling out of dives or learning flips, rolls, etc. You'll likely need to use a timer when you fly, but they will not be too hard on your batteries.
Like all of our 803 motors, these babies come with real bearings installed, adding to the smoothness and longevity of the motors.
