I have been using iflygps for 2 years now and I have used Raim arms and iPad holder for use in the Cessna 162 I rent. They did not always work very well, the iPad holder is too big for the iPad mini4 and the arms arm big thick and limited in movement.
At Oshkosh last week I saw the Mygoflight iPad holder and arm with suction cup. I used it on my flight home and what a difference. The way the iPad is held is much more secure and it is not a big case. It is a diagonal arm with click system to attach to the arm. The arm can be fixated with one knob and the flexibility is much better. Here is the link for iPad holder https://www.mgfproducts.com/sport-universal-cradle/ and add the screen protector it takes away the glare off the screen. This way you don't see your own reflection anymore. And here is the arm https://www.mgfproducts.com/sport-mount-flex-suction/
It is great to see option improve so much.
