Description
What is SFOC?
FETtec SFOC (Simplified Field Oriented Control) is an innovative approach to control brushless three-phase motors, enhancing efficiency, lowering current and torque ripple, and improving response times. With FETtec SFOC, users can experience up to a 13% increase in efficiency and up to a 30% boost in acceleration, alongside other benefits such as stronger sensorless motor startups, reduced noise, and smoother motor operation.
As of 18.12.2024: Betaflight passthrough is supported up to version 4.5.0. Compatibility with later versions will be made available through future firmware updates.

Recommendations
Generally, we recommend using the provided capacitor and a FETtec Spike Absorber (when used with up to 6S).
When using an 8S setup, an appropriate flight controller or FC must be used, and an additional BEC may be required.
