I have heard from different people that if you boil your plastic RC parts, that it will make them stronger. That’s all well and good, but I have never heard the science behind it and because of that, I felt it was something that I may eventually try. However, the team over at RC Car Action have posted a great article that details the science behind the process and features how-to instructions and input from Richard Royal of RPM RC Products. After reading the article I can say that if you find yourself frequently breaking certain parts, you may want to try boiling your next set of parts before installation. Boiling parts can also benefit older vehicles, the plastic will become brittle over the years and boiling the parts will help to restore some of the original flex.
