Know before you buy
The 21Nm motor provides high-fidelity, sustained torque that allows for detailed force feedback, making it suitable for both endurance racing and competitive sim setups. The direct-drive system ensures that the feedback is immediate and lacks the mechanical lag found in belt-driven bases.
Zero-cogging technology eliminates the 'notchy' feeling often found in some motors, resulting in a significantly smoother steering rotation. This allows you to feel subtle track textures and tire grip changes without mechanical interference.
Yes, the Pit House App is the primary interface for configuring your wheelbase settings, including force feedback intensity, steering range, and firmware updates. It is highly recommended for fine-tuning the base to match your specific driving style and individual game preferences.
The R21 features an intelligent thermal management system specifically designed to monitor and regulate internal temperatures. This ensures consistent force feedback performance even during extended, multi-hour racing sessions.
The 21-bit magnetic encoder provides 262,144 points of resolution, which translates to extremely precise steering input tracking. This high level of accuracy ensures that your in-game steering movements perfectly mirror your physical inputs on the wheel.
Given the 21Nm of sustained torque, it is essential to mount the R21 to a rigid, high-quality sim racing cockpit or a heavy-duty wheel stand. A stable mounting surface is necessary to prevent chassis flex and to fully experience the detail of the force feedback.
