Seing many people like this model, i wanted to say thanks :) I would also like to state i am not responsible for any damage done to your bricks during building or driving. Even though this truck is my best trial truck so far, it can be still improved. There may be some small problem with rear universal joint touching the XL motor. Other than that the truck has no major problems. Good building! And thanks for the positive response! email: zblj87@gmail.com
