I ordered the kit as a whole because there was a discount in so doing. There were quick build wings and fuselage. In addition, 5 crates of parts to complete the aircraft. Even though the aircraft is designed to be built in stages corresponding to the 5 boxes I decided to inventory all boxes. This way, I could order the missing or damaged parts at once. This took considerable effort and I much appreciate my brothers time in this effort spread over several days.
