This was my first scratch built jet,the Su-57. We built this for an Aeromodelling Expo at our college. It took about a week and a half to complete, including the paint job. I dedicate this article to the members of the team who were instrumental in the construction of this mighty jet.
Used 3mm foam board and lots of hot glue.
We started by designing the plans on Adobe illustrator and printing them. only the main parts were planned, like the wings, vertical horizontal stabilizers the rest all were made by trial and error.
