Whilst your example states the same situation, the price points are far apart..... So I cannot really connect to that kind of situation. "Model" trains and cars (sorry no).
My posts were simple, when Hornby had them people complained, and when the don't have the fans you still hear complaining. Again as I said the term "turning fan" can be taken in many ways, it doesn't say the fans turn because they are driven by a belt connected to the bogie. Turning fan can still mean a fan that freely rotates.
