Hey guys quick question, I just purchased the DJI phantom 2 vision.why do they use 5.8 Ghz for the t/x and r/x if it has less range and its more directional why don't they use something on the lower bandwidth (2.4) Cost? 10 years ago I used to fly third scale gas airplanes so I'm kind of out of the loop with this new stuff. Thanks for any help...
