ORIGINAL: Cal-Torque
And, really, the Titan/TBolt is not an original design. Take any 1/8 pan chassis design, modify it for gas, and voila! The Smartech versions look especially like Hobao/Ofna. The diff cases even have sway bar mounts... Forward thinking, or direct copy?
Direct copy?
We just make a 1/5 4WD that can have 1/8 racing features and functions and easy to handling, is that called " direct copy?"
