-I can't find the source right now but I have read the whistle was actually due to airflow/around through the gun ports.
-Our 51 had custom plugs in the gun ports. Whistled just fine )"
Hi everyone;
In perusing the forums concerning Mustang sounds, I've come across several postings concerning a desire to hear the famous P51 "whistle" in soundsets.
A2A has produced by far the most authentic sound set for the Mustang I have yet heard done for flight simulator.
Just a few words about the "famous whistle" if I may.
When you attend an air show and hear a Mustang going by you at low altitude, what you are actually hearing is a whole lot more than the Merlin.
The famous sound of the Mustang changes as it's heard on the ground due to various and constantly changing factors that include the following;
1. The power setting; during a display demo maneuver pass most likely up at METO (46" 2700RPM)
2. The outside air temperature and density altitude at the time of the pass.
3 Most importantly, the sound you are hearing is augmented by the air passing through the radiators beneath the airplane coupled with the above. There are 2 doors under the scoop. One controls the oil temperature and the other the coolant temperature.Usually, during a demonstration where you might be viewing a low flying Mustang , the oil and coolant shutters are selected automatic, but if the temps are high due to extended power settings at Meto or above, the pilot might have both shutter doors open manually. The actual position of these two shutter doors at any given time will change the sound you are hearing and most certainly are responsible in large part for the famous Mustang "whistle".
Just a few words here from an old hand in the hope that those of you enjoying the magnificent work on the 51 done by A2A will come to appreciate how difficult it is to produce a complete Mustang soundset.
