The 1/18 Rally and I am sure the Tenton have a lot of small Philips head screws in them. Do not ever put a Philips screw driver to them as they strip super easy. Find yourself a flat head that fits well into the screw and use that and you will enjoy a long life with these screws. Also this tip bail you out if you already have a stripped screw. That is how I got one out and conceived of this tip.
