Hey, just wanted to throw this out to the simhat community. I hope the developer doesn't mind, because I know it is supposed to be worn on a hat, but... I actually mounted my iphone to a camera tripod. I put the tripod on my right or left side right next to my chair depending on if I am flying DCS or Xplane 11/FSX and depending on where my other flight controls are. With the control arm of the tripod, you can get such precise viewing and great "return to center" control. I can control speed of movement, the up, the down, right and left, everything. I highly recommend giving it a try. I did the ballcap thing for a while, but I find that the tripod method just works better for me. And it is so much better than the hatswitch or any keyboard commands you could program for viewing. Give it a try.
