I will agree with you on the socket head cap screws. They are so much nicer than Phillips head screws. Here's a little tip for you. To ease the pain of threading the screws into the plastic parts, get yourself the corresponding tap to match the screws you use. For Tamiya rigs, it's mostly 3x.5mm threads. Anyway, run the tap through all the plastic parts before you assemble them. The tap will cut the threads, which means the screws will run right into the holes like butter. If you are worried about them fitting loose, don't be, but if you want to be sure they don't back out, tap about 3/4 the depth of the screws you use for each hole. That way the screw will cut it's own threads the last couple millimeters and that will keep them tight. You could cheat and use a cordless drill to speed up the tapping process too, but be careful not to go to crazy with the speed. Clean the plastic out of the tap flutes after every hole.
