Best efficient 4 inch drone

Today I broke my personal record with the Geprc Tern LR40 #fpvdrone and flew 12 km long range FPV.
The drone is simply super efficient and in combination with the Li Ion battery from Uruav Flight times of over 15 minutes are no problem.
I already tried to complete the same flight with my 6 inch #iflight #nazgul #drone but unfortunately I had to abort the flight because a strong crosswind would have made the return flight unpredictable.On the current flight I had a constant headwind and was therefore able to better estimate the return flight and the consumption on the return flight. In the end I only have a third of the battery capacity consumed.
URUAV VTC6 18650 4S 14,8V 3000mAh are definitely a good alternative to well-known brands like #iflight or #geprc. Thanks to the O3 unit from #dji there is no need to mount a separate camera on the #fpvdrone, which also saves space and weight.
So long #cinematicfpv flights are no problem at all.
As always, have fun watching, see you then 🫡.
