Good intel!portman wrote:You've picked the right choice - the aux intake flaps were spring loaded I think, or maybe just opened by airflow??? but anyway - when parked the bottom flaps were closed and the uppers open due to gravity. When sitting on the ground with the peggy running they would all be open and in fwd flight they would all be closed.
Just a dumb luck choice, on my part.
