Default Re: Air intake noise made my jaw drop

You are correct sir! There was a model plane magazine article I read where they used a sound meter and concluded that once the exhaust was made nearly silent the same amount of noise was coming from the intake.

For years Rotax has made an intake silencer for some of it engines.
