7-inch drones are "special". They are not as smooth as 5 inchers but they shine in terms of range. Cruising speed of 50km/h, 8 minutes of flight and it easily can fly a distance of 5 kilometers before the battery runs dry. I never really flew it that far, but it should be doable with the equipment I have over there.

What I'm showing over here is based on iFlight XL7 v2 carbon drone frame with some "special" motors. But everything else is almost like in a normal racing FPV drone.
