I have a bvm F-16 that flies with a dynema/ scorpion 630kv 12s 5300mA. I also have a un-bulit green fuse/scale gear Yel F-16 C.
The entire air frame ready to fly is around 16.25 lbs. It also has extra weight from the LE flap servos and hardware.
Still dead stick landing on a gradual slope holding decent air speed (no flaps deployed) it's still forgiving.
