Andy007RC After driving the car with the metal upgrade kit I’ve discovered some things you’ll need to fix BEFORE driving. All parts are metal which means screws used on metal parts come loose and fall off with the vibrations the car makes. I list two screws on the steering assembly and one of the very little screws that holds the optical axis in the swing arm. What I have done to fix it is to use Loctite on ALL screws. This isn’t an issue so much on the original parts as they are plastic and the screws naturally have a better grip as plastic is a softer material.
