Hello all you long range experts I am looking into ordering a set up for better range and am trying to decide between Dbs or Fpvlr? I am thinking I am going to start without boosters. Can boosters be added later to either choice? Is either one better then the other for areas with lots of trees? I am new to phantoms but am already l pushing it to the upper limits of the stock p4 range and want to keep going. I am getting weak video warning around 6000ft out over water at elv 200ft in a area that should not have much interference that I am aware of. Thanks for any tips. I have heard this is a opinionated subject so let's hear some opinions.
