Hi guy's, thought I would share what I've done to my son's christmas present he will be receiving here soon. I picked up this sc truck for not a bad price for what you get. With all the research I've done on this truck, it is really durable and makes a great basher with a few upgrades with stock drive train it is wicked fast and surprisingly can take the extra horsepower. Here's what I did, First, I replaced the stock motor and esc with the Traxxas Velinion brushless system. Second, I installed a 3 cell lipo. Let me tell ya, she really comes alive. Third, put a set of Axial Wraith tires and wheels. This thing is now a blast to drive and really fast. When you lay on the throttle, it pulls wheelies all the way across the yard. I added 50 weight oil to the shocks for those jumps. Another good mod to do is buy $5.00 sling shot rubber tubing, cut a one inch piece for all for dog bones. Slip it over the diff and dog bone. This solves the problem of the dog bone drive shafts coming out and helps save them from getting bent. I got that idear from another posting some where. But it works great.
