I need to get this right too please! Looks like the nose ring is holding the non moving part of the engine just before the drive washer .Wouldn’t that though put a lot of stress on the engine body? I used the same Dubro soft mount for an OS70 4s on a trainer last month. Well the trainer did go down in an uncontrollable fashion and crashed .I believed at the time that that was due to elevator’s clevise/ horn clip got undone. In that flight I had used the Futaba 7c 2.4 GHz system, the soft mount and the new trainer all for the first time. It couldn’t have been due to the vibrating soft mount could it?
