I thought it was really quiet.

Certainly not as a loud as my vacuum cleaner.

I was up for so long and having so much fun that I had to strain to hear if the motor was still on. Even when downwind.

This Multiplex doesn't seem to make it into the top 3 list of best starter/newbie planes. That's unfortunate. I had so much fun today. Even my buddy who has flow big gas planes thought this was a great little plane.
