Ok, here's my entry! Bet you didn't see this coming!
I didn't have time to put up any big scale track and stuff, so I decided to pull the freestyle with a micro truck! I just had to modify it a little to get some more flex out of it, and I printed tiny planetaries and some steering upgrade parts for it too. This truck is so bad and hard to drive on a small track like that, because the electronics are so bad, that every time you steer, it draws a lot of power from the motor and the truck slows down A LOT, so it's basically a point and shoot type of truck when you drive it!
It was very hard to get the thing stay on it's wheels the whole time, so I literally took almost 350 shots before I managed to pull a long enough freestyle! I felt I was playing some crazy hard video game level I just had to beat, LOL!
I built a quick freestyle track, and 3D-printed a few crush cars too!

Lighting is pretty bad and all, but I hope you can still watch it through! Shot in 50fps and played back at 25fps. THE DRIVER HAS NO SKILL WHATSOEVER, SO IT'S PURE LUCK THE WHOLE TIME!!!
