1/16 tankss (not counting the gun) is about the same size as 1/10 cars.
Get a 1/15 Bandai Tiger 1 lah, not too expensive (1/2 price of tamiya but not so elaborate), good size to fight with Tamiya tanks. Cheap wor, 財政 will not 少呀~ 周百通 showed a 1/15 tiger on the #9 post on top here, the one on the extreme left. Slightly bigger than the tamiya 1/16 Tiger (second left).
1/24 are too small for any outdoor cross country run but good for run at your bed... but I am not sure if your 財政 may 少 you because you have a 1/24 girlfriend in the bed 呀
I was suffering from this kind of comments for many many many years because I have 3 elder sisters at home!! Those 8-women can only see '阻地方!嘥錢!' and I had suffered enough from them.
Lucky I moved away for a long long time and I am a happier man now with no 8-women next to me to make stupid comments.
Now I have a very understanding wife All I have to say to my wife is: 'look, I do not mess around, don't drink, don't gamble, only go to work and go home, don't you think I deserve a little bit of not-too-expensive hobby?'
