It has it's problems,but they're not insurmountable. It's major problem is a lack of chassis reinforcement,which can be easily remedied with a length of 15mmx15mm aluminium angle,cut and drilled to suit. It's a reasonably resiliant chassisthat's very easy to work on and upgrade part can be found quite easily. It's other real drawback is a lack of steering,which I'm working on at the moment.
