For those who love the sound of a Rolls-Royce Merlin, imagine having *four* of them on a single plane like the Avro Lancaster. Fortunately for us, the Bomber Command Museum of Canada has a non-airworthy Lancaster in their collection that they occasionally run up. Rumor has it that even a short demo costs them over 800 Loonies in AVgas.
Here's the audio of a three-engine run up on YouTube (fourth engine's prop was out for service). Grab your headphones and enjoy the Merin music.....

I see that it is cannon-armed rather than machine guns. So do you know if it is an F4U-4B or F4U-5?
