Hi I am New to the forum and also am thinking about getting a Revo 3.3 or an MGT. My Local Hobbie shop Has both of them in stock and to answer your question about size the MGT looks bigger. I Like the Revo and The MGT but Have never done Nitro MT's or otherwise but I own a T4 and B4. My Application would be bashing paln on getting one or the other and am going to be bashing alot so already planning to get RPM Arms all around but can't decide on which to get please help me out also thanks.
