Group N ran into the most issues with the final performance test. The energy greatly increased when the caboose was attached since it blocked the air flow for both propellers. With some more time to fix the code, the group might have been able to reduce the energy use. With the code being used, there were issues with the reflectance sensors sensing the distance traveled when going up the incline with the caboose. The group decided to use an older code that worked with the reflectance sensors. The group was able to complete the final performance in one test.
