There is a RadioCraft 35% with a DA 100, Slimline mufflers, and an Air Models 28 x 10 that is probably the quietest 100cc at our field. I fly the same engine and mufflers but use a Mejzlik 27 x 10. I think the Air Models is a little quieter.

Many have said it, though. The biggest factor to noise is the position of that throttle stick!!


Take care,
