i inspected the buggy , and the engine is a jp .21 with 10 tanks on it and proper beak in was done but the screws are all rusted , the hobby shop is selling it for someone so i told the guy at the  hobby shop to replace all the screws and clean the car then i m8 consider buying it if everything works fine , and no it doesnt have big bores but i might replace the shocks with the s8bx 17.5mm big bore shocks they seem pretty good
