I have a spare for just about every part of my buggy. I may never need them but I'll be damned if a $2 part will keep me from completing my day of racing after I have driven an hour or more depending on where Im gonna race. Im heading to the Rc Pro Series rd #2 in Wilsonville, Al on June 5th, its 4 hours away. It would be pretty stupid of me if I didnt have extra parts. My first hobby is racing, my second hobby is buying parts so I am ready to race. It kills me to see someone at the track have to call it quits because they broke an arm or something simple. Be prepared DREAUX !! Always !!!
