The professional Sim racing community are no longer interested in the product produced of the 3 giant manufacturers (Logitech,Thrustmaster,Fanatec) Nowadays all projects are for Direct Drive simracing steering wheels or the Open Sim Wheel aka OSW
I already started to assemble what's required to build one of these.
The OSW DD wheel uses a brush-less servo Motor similar to the ones found in CNC machines as a base! The base is operated by a servo drive that can read from the sims that exports telemetry data.
