Serpent SRX8 "Cobra" 1/8 Scale Competition Nitro Buggy Kit
The easiest Pro car to build! I tried many of the pro kits. (X-Ray and Associated is still on my todo list). Good overall quality. Drives great, the setup in the box is not for me so i used Ty Tessmans setup from the HD-815v2 kit, Oils and changed the springs to softer than Tessmans. Easy to access the diffs.
