The lanyard was a great addition to the maker racer MK3 from an engineering standpoint, but speed isn't everything. I tend to spend a lot of time working on the inner workings of a project (because of my engineering background) but the visual appearance is just as important. For many, the visual appearance is what makes the initial impact. For them, "What does it look like?" is a more than "How does it work?" It was this bit of insight that started to next Maker Racer iteration. This version took all of the mechanical aspects that ha been developed for the MK3 and put them in a more attractive form.
The hard edges were removed and the bulky braces were replaced with thin clips. We also got rid of the decals (which may have been a mistake.) The overall effect was a much sleeker looking car. The new version also gave the user easer access to the drive axle and a better way of clipping the lanyard to the car body. And there you have it, the Maker Racer MK4!
