Here are all parts for my LKTR250 Quad. I decided to make new arms from 10*10mm aluminium instead of 3d printed ones. I took measures from the 3d printed arms and used the same hole spacing. This way I can choose between them 2. THe aluminium arms have 2 holes so I can extend the arms 8mm if I want to. As the aluminium arms only have 1mm material I had to shorten all 8 screws that holds the motors in place. All wires are long enough between motors and ESC’s. NExt up is to add 2 flimsy wires that will power a piece of LED-strip front and rear.
