it's the correct application of yaw (rudder), roll (ailerons) and pitch (elevators) at a particular speed that result in the best turn rate
G-force equality does not co-relate directly to turn rate / radius at all between different aircraft !

Sorry, but this is demonstrably false in IL-2 and also in real life. Fly straight and level, roll the plane into a bank using ailerons alone - it will start to turn. With any significant bank, the nose will also tend to drop, so you need to pull back on the stick to compensate.
The only use for rudder in turning is to 'keep the ball centred' - to avoid sideslipping or skidding. In tight turns with a prop-driven aircraft, most of the forces generated by the rudder are needed to counteract the gyroscopic forces from the prop, which is why you find yourself having to apply 'inside rudder' when turning one way, and 'outside rudder' when turning the other.
And at a given pressure altitude, airspeed and angle of bank, in a coordinated turn (i.e. no sideslip), the radius/rate will for most practical purposes be the same for any aircraft. This is down to simple physics.
