Hi ADI, may I know how much weight is your DF and how much current it draw when hovering (sorry if this has been mentioned before as I'm lazy to search the whole thread again)? Mine one is not exactly 600g but it's something between 550g - 600g. I feel like it's a bit heavy and the power consumption is too much. My flight time is less than 5 minutes. I'm using a 20C Li-Po battery, so I assume that it still can handle the current (I never measure it before). but anyway my battery will become warm after flying for sometime but my motor is still considered cool...
