Introduction
RC Cars are built tough these days. They are also often built to be very powerful and eventually the power in these vehicles can out pace their toughness, so a part will break! A-arms, being the part that takes the most beating because they are the connection from the tires to the chassis, are typically the first to go. There's no need for your day of fun driving to be ruined however by something that can be fixed so quickly and easily. Don't take days to let a hobby shop or friend do your repair, do it yourself!
