Me and a buddy got ours in mid Feb. he had some trouble with his motor and i started after about 1/2 gallon of fuel so i put an LRP .28 spec motor and it is a blast.The only thing i did was change tires to the Buggy style and made a big change in it....i was running 2nd in a local race until i ran out of gas....still finshed 5th in a TRUGGY clash.
