Despite facing challenges in designing within constraints, adhesive-based Valcro provided an advantage for maintaining a low weight of 4.2g. Grabcad print service was utilized to prevent errors during model printing and resolve issues. The model's structure details are outlined in a presentation that also includes a method statement. Key forces include electronic components weighing 42g (0.412 N), motor thrust of 120g (1.177 N per motor), wires at 25g (0.245 N), battery weight of 47g (0.461 N), and a payload of 250g (2.4525 N). The model also includes motors weighing 26g (0.255 N), main electronics contributing 0.28776 N, electronic speed controllers (4 pieces) totaling 0.28776 N, and four motor thrusts of 1.1772 N each. To ensure stability during flight, three key conditions were established: fixed thrust area (weight of components), a payload surface with the weight of components and full thrust (more than just a payload), and no payload or thrust while standing on the surface of thrust, accepting a minimum force of 0.01 N when zero force failed the simulation. The optimized frame design represents a balance between weight reduction and successful printing, allowing for further weight decrease but with potential challenges in printing or assembly stability.
