I had a little fun with 17.5 powered inline Xti this weekend at the Timezone GP. I put it P2 on the grid and was fortunate enough to grab the W. Randy was exceptional with his kit Xti at IIC, so I was easily inspired for this project. I wanted to make sure that I was using the latest springs (except fronts). This was a straight forward build with nothing funky done. The idea was to get a little more weight forward to reduce front tire slip in effort to see if I can reduce post run fade.... more so at club tracks then big events. I reversed the esc and battery location which makes the wires much shorter and efficient. I did have to use a piece of double back tape under the battery plate to keep it from sliding into the servo. On my car, I did have to sand the football a little to snuggle the esc a little closer. I wanted the shorter wheel base, so I chose the Altered Ego chassis which builds up at 197. I did use the Xti rear plate. I want to say the stock Xti chassis builds at 203. This car drove really well! I built it a week ago. I haven't raced stock since last spring but to my surprise I nailed the set up. Didn't lay a wrench to it all weekend! Now that's lazy racing.
