I did the itelite/fpvlr upgrade on p3 controller and removed antennas, place just 1 of them on my friends p2v+ and doubled range! No booster app,but does use fpvlr antennas unboosted on remote. He usually got 4000-5000 ft, i've done 3 runs so far and get an easy 9000' & know it'll do a little better but its been windy on those runs. Maybe some struggling p2 users can recycle!!
