Putting together a toolbox for my Tamiya tiger and want to know what spare parts I should carry with it. Already got enough small metric tools to work on it. How about a spare screw bag? Any suggestions.

Super glue, double sided tape, a few small screwdrivers and especially the small plastic black one that comes with the kit to possibily adjust the sound. A few pliers wouldn't hurt either. I doubt you'll need any spare screws for they all should be locktite secured.

Your best friend on the battle field is glue and freshly charged batteries.

I rolled my Tiger and boke the smoke/flare items. Any idea where to get new ones?

Have to find someone with a spare "accessories bag". I have some here, but yeah, other side of the world...
