Neo02,

Maybe some gas engines, but certainly not all or all of the noise. Weight is still an issue with some builders, so 2 mufflers aren't desirable. Soft mounts may take a little power away. Some people want the props that are the loudest or the really big engines. I respect your dislike for engine sounds, but not everyone likes the same things. A lot of members at our club enjoy the louder engines. A few run 4 strokes without mufflers. Personally, since I flew full scale for many years, I need to hear the engine to feel comfortable. It is a habit that can't be broken. I didn't even use extra hearing protection when I flew and thankfully did not suffer hearing loss of any kind. (I was tested every year) I can sense a lot from a good level of sound from my engines, and I depend upon it. We were talking the other day about having Walkmans or iPods at the field when flying, and almost everyone agreed that they would be uncomfortable not hearing their engines.

Not everyone can enjoy all things at their field. I sometimes miss the scenery of Europe and think of the beautiful fields that I visited there. Some people have noise restrictions and some don't. Some have ridiculously short fields or have hazards. We have to take what we are blessed with or without, and wish the best for all of the other r/c fliers elsewhere. If I had to fly under hardships or restrictions, I wouldn't wish that for anyone else just so we could all suffer together.
