I have a Gator soft and safe mount in my 2m Majestic. Motor is a YS140dz. My question is do I need a nose ring. Now I personally would have thought a nose ring would be against the principle design of how this mount works but after around 7 flights its floppy all over the place!. I have checked that all screws/ mountings are tight and secure etc. The four mount grommets are compressed as tight as possible (limited by the spacers in them). Anybody had any experience with this mount/motor combination? Is the grommet rubber prone to nitro degradation??
