What FPV equipment(TX/RX) are you using sir? And what is the max range you were able to pull out of it?

it has done over 60 successful flights at the highest reaches of Himalayas, regularly pushing  mks boundary . HK LRS and video eqpt, TGY Radio, 10000 mah 3S bat

Sorry to bother you sir but can you tell which Video equipment are you using? make, wattage and frequency?

1.3 m,1.5w

Hi sir, What's the longest range you have achieved with HK orangerx LRS..? Is it 100mw or 1w version..?

well, Can't call any, the best, RMILEC  and Thomas Scherrer V6 gave some really good ranges, without drop in RSSI, Orange 1W really isnt 1W is about 400 mw (after flashing the firmware).

Really speaking it isn't the LRS capability that governs the range, it is the LOS and your aircraft range, if you google you will see people have flown to some crazy ranges without drop in RSSI values really (Provided you were within the LOS)
