I have a BME 50 mounted on a GP 120/180 Engine mount. I have noticed that the Mount becomes VERY flexable after the engine is warm. I can flex the mount 1/4in plus, both up and down. This makes me very nervous and have not maidened my WH Extra because of this. I am worried the Mount will fail in flight.
If anyone has seen this or anything like it or if you have any other suggestions please let me know. I do have a H9 mount sitting here that I might put in place of the GP.
