Well much as I love tamiyas 1/6 bikes (and I do love them) I will never buy another Tamiya plane (I think I will have to give up on their decals and buy some other manufacturers (assuming they do the same markings)) the decals have fought me all the way, breaking up, not sticking, I just hate them, the bike decals seem fine. It's a shame as the kits go together really well.
I know some of you will say now you know why not buy decals when you buy the kit, well unless I want different markings to the one in the kit I don't see why I should pay again for ones that are in the kit.
