Inspire Mini Tablet? Errr no it's a NuVision mini tablet. The props weren't spinning as the contact with the deck had stopped the motors therefore I was able to grab the top of the battery and remove it before any other unpredictable event occurred. Ibflyin, thanks for your advice. As you will all be aware, the unit doesn't come with anything like a full operating manual. I have now downloaded this from the DJI website. Yes, it was a controller calibration issue combined with unfamiliarity with the mini-Tablet. I flew the Quad today for about 20 minutes and now have a better idea of it's performance.
