Well I have a pair of metal mounts already that are not anti-vibration from Hangar 9. I must admit though, I haven't heard the "do not use" anti-vibration mounts. In fact, I read an article in the December 2013 MAN about why you need them. Maybe not Dubro exactly, but you need to keep the vibration from the airframe as much as possible. I haven't started putting the 125 together yet, so I have time to do more research.
