Hi Pushkar

I am wonder if you can tell us if the ultra puts out less noise on a carbon fiber frame than either the Titanium or Aluminium ?
Since it's exactly the same motor it shouldn't be much, but there is a video in another thread discussing how some frames are amplifying the sounds of motors that sound not as noisy in other frames.
