This is a different challenge because only parts of the first version of SP are allawed. There is no limit of number of pieces. BUT you are allowed to use 3 parts of the new versions of SP as me with the plane that I create with a landing gear of the new version. I think that this challenge is interesting because this pieces are too simple to make good replicas or wat ever you want to make. This is my first challenge so I don't know how does this work. 1th place 10 upb. 2th place 8 upb. 3th place 6upb. Please forgive my english spelling I don't write it very well and my movile phone's corrector is always translating every word to spanish.
