Both models are built around an all-new flat-wire motor technology, a design approach borrowed from aerospace and electric vehicle engineering, making them the first sim racing wheel bases in the world to use this architecture. The result is a zero-cogging motor with 26% higher torque density than comparable competitors, delivering a force feedback experience that is smoother, more detailed and more consistent lap after lap.\u003c\/p\u003e\n\u003cp\u003e The \u003cstrong\u003eR21 Ultra\u003c\/strong\u003e outputs a sustained 21 Nm of torque, paired with a 21-bit magnetic encoder resolving over two million steering positions for extraordinary precision.
