Wingtip modification is one of the methods to improve the performance of UAV in a cost constraint and simplicity worth considering. In this study, the low-cost wingtip modification is manifested by using a readily available 3mm plywood and laser-cut to form a flattened Whitcomb winglet geometry as the base design. This low-cost wingtip modification is implemented to Senja UAV, mapping, and monitoring capable UAV developed by Aksantara ITB, a student-led UAV research team. The original design of Senja UAV incorporates a blended winglet design. In this paper, the performance of Senja UAV with 3 different wingtip geometries, namely the flat-plate Whitcomb based geometry winglet, blended winglet, and winglet-less, are compared using CFD investigation. The results had shown that flat-plate- Whitcomb-based geometry winglet is capable of reducing induced drag. However, it is still less capable than the blended winglet design. At a low angle of attack, its profile drag makes the performance, in terms of CD, worse than the winglet-less design.
