4km Long Range with Flywoo Explorer LR analogue

Logged my longest flight distance so far at 4.2km from takeoff point. Cloudy and gloomy day but was glad the GPS managed to pick up satellites by powering up via USB before plugging in the battery. After a quick test flight, replaced the battery with my DIY 18650 4s 3000mAh and took to the skies heading straight towards the destination.
With the original Explorer LR analogue that comes with Goku VTX625, power was set to max at 450mW. Surprisingly, video signal was still bearable at turnaround point as I maintained a fairly high altitude while control link was still rock solid with the Tango 2 set on dynamic power up to 1W, but I think it only ever had to switch to max power at certain points where I didn't have enough altitude.
