Have phantom 2 H4-3D
Want the easiest, least expensive way to FPV with an iPad mini.
Is there a range extender with this set up??
Will it allow you to use ground station as well?
After few flights, range of phantom 2, seems limited.  
Thank you for any help

If you want to fpv with phantom 2 h4 3d you cannot use i pad.You need 5,8 ghz tx and rx and a monitor.If you use wifi conection from your go pro to i pad to see the live view your range will be limited you will have lag and the most important is that is very easy to mess with situations like crash or fly away because go pro and phantom will be using 2,4 ghz both and that will cause problems.
