I have assembled my T-Rex 600e to the point where I have the electric motor armed, but have not fitted the rotors. Is it normal to experience a fair bit of vibration when you rev the motor right out? As I understand there should be no vibration when you have fitted the blades and balanced them, but I would have thought there would have been minimal vibration with no blades fitted. Your advice would be much appreciated.
