it is not very light.
whole build with no battery is about to 200g. 1500mah 4S lipo is 250g or so, so, it pushes those motors a bit much.
stack i used was this one:
it is not only stack that is heavy, it is motors. plus lidar, gps, esc8266 board, r-xsr, foxeer camera - it all adds up.
motors are brotherhobby T1 1407 3600kv. i could have used bigger ones, i think, it would be better. something with bigger stators that can still mount in the 1407 format.
