I went out with my P3A and had a great time flying today...until I was done and walking back to my car and my tablet slipped out of the mount and fell to the groung and shattered the screen. Luckily it was a cheap acer 8" tablet ($80)....but it did work perfectly with the GoApp....no lag at all. I had done what so many others here have done and replaced the plastic foot with a metal one and this solved the wobbling problem. The issue I had was the actual plastic part that clamps onto the tablet. Because of the slight curve of the back of the tab the mount barley held onto the edges of the tablet. The top and bottom plastic hook part of the mount were barley gripping the edges. It always seemed it was ready to almost pop out. Anyone else with this problem or any suggestions? Maybe it was unique to the tablet I was using?
