well just bought one thursday and ran it yesturday for the first time at LRT raceway in Waterloo IA for the annual Roat and Race...truck is f-ing dialed! ended up qualing 3rd and won the main, truck was on rails and was very easy to drive. only issue I am having is when I hit the brakes sometimes it makes like a grinding noise? everything feels smooth when rolling it by hand....and brakes r not locking up so I am not running to much brake?
