Subgenius213Hi Subgenius213,
The H502E does not have a screen on its transmitter providing a live feed, its also equipped with a 2.4ghz transmitter. This drop is for the H502S w/Live FPV feed to its 5.8ghz transmitter via a 4.7" LCD screen.
DaveHoffFor those of you who may not be aware, the fact that this is 5.8 ghz is good. Less interference. Perhaps a little bit better range in terms of reliability.
