The Trackimo Holder is easy to install. There were no instructions like be sure and put it on the Port side of the aircraft so it is less likely to interfere with the compass. Seems to be well made. I would recommend adapting the lanyard that came with the Trackimo as an anti-ejection on impact safety device. While the holder is easy to install, I'm left wondering if I should install longer screws? There seemed to be a good grip and I used locktite to help keep them from backing out. Communication with the vendor could have been faster. Not sure if the item was instock or if it was printed on demand. Still I think it only took a little over a week to arrive. It's on my Phantom 3 Advanced now waiting for the weekend to fly!
