On the technical side, a more precise timing setting is now possible, while the timing range has been precisely adjusted and optimized from 14.5 degrees to 34.5 degrees. The specification dual axis balanced sintered rotor with red balancing rings now also features a longer mounting surface. The internals were updated all around for higher efficiency and vibration free operation, while smaller dual precession 4x10x4 ABEC-5 bearings provide very precise running and longevity. The new PCB board specification ensures even lower resistance than the previous model. The unique waterproof PreciSensor assures precise operation with any speed control and offers additional advantage when paired with Nosram ESCs.
