Upgrading to Walksnail Avatar GT for Long Distance FPV

My Dragon2 just got a new Nose. Before it had an old DJI Air Unit, with a hard limit to 13.5km max distance. New VTX is a Walksnail Avatar GT, limited only by the Antennas. Should be fine for 40-50km max distance. Let's see how it goes, last flight with the old System was around 35km of travelled distance, using less than 50% of the 6.2Ah 4S2P Liion.
