Got me a Venture 30 - very neat machine! One problem, during my tenth flight, the muffler broke off - the tube between the engine and and muffler broke off where it meets the muffler. From the oil residue it seems as if it cracked off gradually. The supplier says that I mmust have serious vibration on the heli. When flying the helicopter, there is no foaming of the fuel in the tank. Is there any way of checking for vibration other than the fuel in the tank?
