Did you ever fly the army version?
No I haven't Woody and now that I think about it, I suppose the Army version was more stripped down with less insulation. So, I guess they would be much louder than the Civilian version I flew. In any event I guess the question is did the noise in the Electra inhibit communications to AE and FN?
Now you have it right about the Army version. Those twin augmenter tubes on each engine would really rattle your brain. If I remember correcty, they were only 340 hp but the higher operating RPM, about 2400/2600, I think, helped to increase the noise level over the Wasp Jr. too.
I think you are right about the real question and I have no doubt that the answer is YES, YES, YES.
By the way, I was not trying to compare the Twin Bonanza to the Twin Beech. I've never been inside of a Twin Beech and have never even seen an Electra.
