TheSAVÖX SB-3290SG servo is a brand new patented technology developed by SAVÖX.

With the new SB-3290SG servo, Taiwanese manufacturer Savöx has once again made a revolution in servo drive technology. The newly developed eight-pole AC motor of this "monster" not only provides a lower weight (72 g) compared to its predecessor SB-2290SG (81 g), but also higher efficiency and significantly lower heat production. After 5 minutes of operation, it remains up to 20% cooler than the SB-2290SG model. This significant improvement means that the servo delivers maximum power for much longer, and the model is much "harder, more direct and more accurate."

Thanks to the latest technology, the SB-3290SG tube is much quieter and almost inaudible during normal operation. The well-known "beep" of digital servos has been almost eliminated without having to accept any drawbacks.

Especially in extreme flights with heavy loads, there is an unparalleled increase in performance. An all-new motor design with a newly developed 32-bit MCU (Motor Control Unit) carries many advantages that offer ambitious 3D and aerobatic pilots new possibilities in flight.
By comparison, the SB-3290SG's resting current is about 80 mA, while the SB-2290SG requires about 250 mA.

The lower weight is particularly advantageous for large models weighing up to 25 kg. When installing the SB-3290SG servo, a difference of 9 grams per servo is clearly visible, making it easier to find the ideal center of gravity.

The SB-3290SG was tested for several months in countless tests by the best pilots in Germany and improved step by step, until we reached the point where we can talk about a real revolution, not just a product tuning !

To facilitate individual wiring, the negative pole of the cable is no longer completely black as in the SB-2290SG, but is now gray, making it more recognizable.

Of course, the SB-3290SG has a soft start, meaning that the servo slowly moves to the desired position as soon as the power supply/amplifier is turned on.

The SB-3290SG servo is suitable for use in helicopters, RC cars and fixed-wing models. The patented SB-329X series will be expanded to include other types of servos in the near future.

The servo features a much larger AC motor, which not only provides high power and speed, but also optimally dissipates heat thanks to its aluminum housing. Thanks to the new motor and gearbox concept, it was possible to add a third ball bearing to the servo, improving accuracy and reliability.
