changes made: primary wings bend more back, put extra horizontal wings at the back, placed a Modded Fuel tank instead for fuel in fuselage and addd extra weight in the front, I saw some flaws in the design at first, for starters as I mentioned before: the centers of mass and lift weren’t in the proper place, the rol controll service doesn’t need trim assistance, yaw controll services are ALWAYS located on the verticle stabilizers and NOT on the primary wings OR horizontal wings. I know that someone else also made a Fixed version, but the creator told me it has trouble taking off so I thought that I could make a better one (not to show off). enjoy your working craft @stevenbose
