I did the pin mod and put in a solid pin intead of the weak roll pin. Other than that Its obviously a single speed g-maxx with a UE idler gear. I removed the vbs because this thing is too fast and if hit something @ 60mph+ I would just cry if anything happen to it especially @ ~$650 a pop not to mention no spare parts are being made anymore. So put it on my now full blown nitro supermaxx that I dont plan on running that much anymore. I also want to lower the body more and the vbs towers wont allow this and duh titanium towers will. Who knows I might put it on the g-4 maxx chassis because that will look awesome. Here the pics of the vbs setup that my previous links broke on earlier in the thread:
