Hello,
I am looking at setting up a QUIET 60 size helicopter for a future scale project. Can anyone please tell me how the 90 version SOUNDS(due to lower rpm headspeed at hover) compared to a 60? Which pipe is QUIETER, the Zimmerman or Hatori?

thanks,
tom

The bigger engines are indeed quieter. In a standard hover, they sound just a wee bit similar to a 4 stroke airplane engines doing a flyby 6 feet off the ground.
