here is a question for you...since traxxas came out with there's and hopefully you can buy just the gear, like you can with the nitro revo, couldn't you just use the gear and put your own cup/internals...ect. on it and help reduce the machine time on the gear, and the cost as well...the question would be, is which cup is a direct replacement and that can hold the 4 spyders that we want...
here is a pic of the traxxas on w/ gear...
here is another question, ae all diff cups bolt pattern the same......does anyone have any info on this....
