In 83 Tower Hobbies had a listing for the Circuit 20 Extra Racing Baja (3045) which looked more like a real car then those previous cage type so, I was SOLD! I ordered the kit and assembled as per instruction pictures as the text was in Japanese. The kit arrived in a medium size box and the car was bigger than I had imagined once assembled. I was already aware of the various 1/8 on-road cars I had seen in magazines, however I was looking for the experience of off road racing.
OS Max .20 R/C was the first engine I got for the racing baja with the optional rectangle engine heatsink (Kyosho SD-75) to keep it cool. As I drove the car more and more I was also upgrading as I was learning to setup all things 1/8 buggy, mostly the engine. Next on the list was a set of front (CB-88) shocks that came with a mounting plate that you bolted to the chassis for extra damping. As for the rear (CB-89) shocks, I got two sets, four all together at the back and a total of six for the entire buggy.
As time progressed I continued to drive the buggy up and down the street and various lots with different types of terrain. That's when I started to notice how the car was handling and ordered the Team CRP (1515 or 1526 Kyosho Coil Over) for the front. At this point the RC market was really evolving and now I was able to adjust the front spring tension and or chose from two different springs; Silver (Soft) or Gold (Hard).
