You can try to make a kt trigger. Buy some kt boards and borrow several sets of templates from the Model Aircraft Association. You can make a fuselage, glue it with hot melt adhesive, fix the wing with carbon rod, fix the aileron and wing with glass fiber tape, and use 22 12 motor for 30 years. The remote control receiver can be 4-way or 6-way, with three to five steering engines. Adjust the battery position so that the center of gravity of the aircraft is 30% of the chord length of the wing. Paddle 1047, decoration can fly, it is unrealistic to do it by yourself, and there will be great problems in redesign. Many quantities cannot be calculated and measured. You can make some changes to the template, but you can't exaggerate. These are all training machines. If the technology is improved, it can be put on a tanker, just like a real machine.
