4inch Long Range Copter

A small FPV copter for the lunch break. It is designed for two 18650 vtc6 or vtc5a liion batteries.

With gps and FC stack you get a flight time of about 20min depending on throttle position. A normal speed of 35 to 40kmh is realistic at 20min flight time. Of course you can build the copter even lighter and without gps. I measured with the gps flight distance of 10km.

Here my 4inch long range FPV drone.

Its not designed for racing but "light" freestyle is possible.

I designed for long flying fun and cruising. It can easily carry a runcam thumb or similar...

Weight is about 220g. In my case i can fly 20min on two 18650 VTC6 cells.
