I have a question about the P-47. I'm not an expert so maybe everything's fine as it is.
As you know, when you start the Pony you can feel the bird is "alive": instrument panels are vibrating and you can even notice a subtle trembling in the wingtips from external camera. In the other hand, everything is strangely quiet in the Thunderbolt cockpit when the engine is running. Very little or no noticeable vibration at all.
I've never been in a Jug cockpit, so I'm asking from my ignorance of the subject, but is this normal? Is the P-47 that quiet when the Pratt & Whitney R-2800 is running on the ground? Maybe work in progress? Can you shed some light into this?
Thanks in advance.
