"The redesign of drone remote control using DFMA method" is a case study to analyze and redesigned the controller product through its assembly process in term of manual handling time, manual insertion time, total assembly time, design efficiency of the design and manufacturing method for the design. The components and manufacturing of the drone remote control were undergone alteration with design for manufacturing and assembly (DFMA) and redesigned methods. The main focuses of this research are to analyze the current design efficiency of drone remote control and improved the design efficiency. At the same time, the redesign was applied to existing model under the same platform. As a result, the assembly time for redesign showed an improvement of 24.93% where the assembly time was reduced from 480.56 s to 360.79 s and design efficiency was increased 1.66% from 4.99% to 6.65%. Therefore, the best design with optimal value is accomplished.
