I just bought a rtr matrix (mail order) and I was very disappointed when I opened the box and saw a mx sport radio instead of the mx 3 that I was expecting. I know rtr's are not known for having great radios but I chose the cen because I felt it was the one of the nicest set up for the money. The mx 3 was one of the main reasons I chose the matrix over the other rtr 1/8 buggies in the same price range. The box has a picture of the mx 3 and says it's included, the literature included with the car states the mx-3 is included, even the cen web site says it comes with a mx-3 radio. My complaint is I bought the matrix thinking I'd be getting a 75mhz fm radio but instead I got a 27mhz radio. I feel a little misled and frustrated. I was looking at the rtr cen truggy but I went with the matrix because I thought I'd be getting a better radio. Now I'm stuck fighting for the same channel 5 clip that a lot of other people are trying to get since 95% of the rtr's use 27mhz. I would have spent more money and bought something else is I would have known this car came with a 27mhz radio. I'd understand the change in radios if I would have bought one if the refurb buggies but I didn't. I bought abrand new one. I can't really be mad at the place I bought it from, they didn't build the car or pack the box. Like I already said, the boxes, cen web site, and every mail order web site says the mx-3 is included. Is there anything I can do to get the radio I thought I'd be getting without having to buy it on my own? At the very least please update your web site so other potential buys will know exactly what they are getting.
