I've had my inspire for a week today. I've logged over 25 flights and I must say i'm very pleased with it. Yesterday afternoon on my third flight of the day there was a very strong vibration at initial take off. The vibration was very strong in gear down and gear up during the transformation the vibration dissipated completely. I landed to check the props and make sure everything was nice and tight. I took off again the vibration was still there I flew hundred feet or so landed then took off and the vibration went away. I took it to my dealer today to have them take a look at it. They said that they experience vibrations with their Inspire as well from day one. They reset my gains back to factory settings did an advanced calibration and took off and landed a few times. The first take off the vibration was considerable, subsequent takeoff and landing's the vibration dissipated and then went away completely. Their analysis is based on experience with their Inspire is that the motors and ESC's need to warm up. I would like to know has anybody experienced vibrations with their inspire at any time? As I said before I've flown it over 25 times without a single vibration. Any feedback would be greatly appreciated!
