Wow..... I'm sitting here scratching my head wondering what happened.... I got my 3rd pair of blade grips in under 2 weeks but it was too dark to fly. After school the next day, I flew for 2 minutes then tried to land on a platform 1x1 foot and 3 inches off the ground. Only one skid landed on it[:@] Fourth pair of blade grips needed, nothing else.... Now I'm serious about the CNC ones.....
