I am getting ready to assemble a Pulse 125 and am swapping out the motor mount. I have seen pictures on RCU where the standard mount fractured. I have a Hangar 9 metal one that I can use, but am also thinking that reducing airframe vibration by using the Dubro cushioned mounts. I am using a DLE 20 and am wondering if I am being overly concerned. The Dubro mount is over $46 and don't know if I will get that much return from the investment. Any thoughts out there or has anyone used them?
