I would like to have a larger screen for flying my MP.....the eyes aren't what they used to be. I have a chance to buy a IPad mini 2 like new (non Cellular) cheap. I know I can cache the map for the intended flying area via wifi at home prior to flying, but can I set my phone as a wifi hotspot ( on site) tethering the IPad Mini 2, resulting in the same live real time map/data/position, I currently get using the IPhone on my unlimited cell plan ??? In other words, get the same fluid real time map data I'm used to with the phone....only bigger !!!!
