I should be receiving my Phantom 2 V+ this week. I'm putting a GPS on it just to make my wife feel better about the large investment. (well maybe me too a little) Anyways, has anyone had any issues with interference from a tracker? Where is the best place to mount one so it doesn't interfere with say the GPS of the quad itself? Don't expect to have to use it, but I found a TAGG on Craiglist for $45 and figure it's worth it for peace of mind. Any thoughts?
