Im not sure which one is better but when I bought my Magmum I also looked at the MT-Spec and the guy at the hobby shop (Machines RC,Sarasota ,FL) told me they were the same. There are up grades to the gears i.e. plastic/aluminum to steel gears which are much more durable. My Magmum is a good basher but requires some mechanical ability when changing gears out and setting up shocks and such which I dont mind. I am looking for a custom body for mine and have been having some trouble finding one. If any body knows where to get a custom body please lease let me know.
