This one is for CEN....I bought a Matrix RTR about a month ago. The motor ran fine for the breakin.. When i finishied with the breakin series, as instructed, I couldn`t get this motor to run for nothing. It would start ...then stop. did alot of research to see what I could do to get this NX26 to run right and couldn`t...Even had some experienced friends take a go at it and they just couldn`t believe that i spent all that money on a buggy and it won`t run...I myself don`t think it`s fair..This is supose to be a 2007 product..I feel as if I got jipped the cost of a motor. The buggy part is fine...should of bought the kit. I know you guy`s have a trade in program...but I feel why should I put anymore money into this product, and why should I trust another motor from you guy`s. I`m very disappointed and very unsatisfied. You came highly recommended and then this. I know now that i`m not the only one. But what I do want to know is, what are you gonna do about it?...I do know that if you pay that much money for a product, it sure as hell better work...Looking forward to your reply and a resolution this my, and the, problem...thanx....CEN_BERD
