I have been experimenting with the OS and differen rubber mountings and back supports. With 500-600 flights on the motor (three motors and three different pattern planes) I have found a combination that at least works well for me. In addition to noise reduction it saves weight and is cheap. The motor mount by RS looks nice but it can be done lighter. 4 rubber dampers at the front and 4 at the back. They are 8 mm in diameter and 6 mm long. Male/ female mounting and 50 Shore hardness. Thread type is M3 and of stainless steel.
Another way to save weight is to use a fire wall made of 1 mm fiber glass cut as a donut.

Henning
