Made some realistic changes like adding 2 motors instead of one, estimate weight is around 1.7kgs and ill be using 12 inch fiber props in this build, the battery will be made up of either 3000 or 5000 cells if i manage to get my hands on them, the rear stab LOOKS small but its enough for this build providing 1 vbar ratio, this with differential thrust the aircraft will have insane yaw authority, which can be increased to even more by just moving the thrust motors a little outward on the wing, i have added the pixhawk ESC and my motor models to the document aswell
