The question is cooling of a pusher during taxi and run up. In a tractor the cooling flow is being augmented by direct ram when stopped but in a pusher it is more of a secondary or induced flow. Is there trouble with overheating of watercooled especially installations in the pusher config when idling around the patch? Automobiles have thermostatic electric fans in the radiator circuit for slow speeds when the air isn't flowing adequately. Some have louvers that open and close to reduce drag.
I have not seen aircraft with Aux Cooling Fans. Is this a problem with tightly cowled pushers? Do people have to shut down their motors to cool them on the ground?
Basically this ties into final weight and balance and complexity of the design I am playing with.
