So I tried some buddy flying with Gliderlink recently. For a while it worked, and my buddy (who is not used to Gliderlink at all) thought it was great. Then we stopped "seeing" each other on the gizmo. I never figured out why, but I think one of us accidentally hit the goTenna "slide switch" and thus turned off the connection. This brings forth two suggestions:

(1) for users, play with it on the ground and get used to the app, so that you can solve app problems in the air without needing more attention than we can muster while flying. It also may help if you mount the goTenna somewhere where you can see it, then if it disconnects you will see its LED blinking.

(2) for Ben: perhaps move that switch to somewhere less prone to an accidental tap, e.g., inside the goTenna status menu item.
