OK, so I bought a little 1/24th scale RC truck, geared for rock crawling. After I saw how much fun it was driving over obstacles, I decided I needed a little indoor terrain park for it, and got to work on this thing.
It's 4 feet x 5 feet, and made of XPS rigid foam insulation board. Carved, glued up, painted, and with some sticks from the yard cut down to make this "log" bridge. I did this over 2 weekends.
It's painted in earth tones, the purple, blue and yellow tones come from my LED lights.
