Sometimes you'll find out that even wargaming can be "try and error". The Macross models I ordered in 1/100 scale stand about 15cm - 17cm tall. WAY TOO BIG for what I want them to resemble (tank equivalents). :-(
Now I spent an endless night searching the internet and found the exact same models again, but this time in roughly 1/200 scale. This means they are going to be about 3 inches tall. About three to four times a 15mm miniature in height/width. Perfect!! (that is like an M1A1 Abrams proportions compared to his crew, so that's exactly how I imagine my war walkers)
There is also the old Wizkids Mechwarrior "Clix" system, that has some Battletech designs in a size that would fit a medium or light class "Armoured Battle Suit".
I got myself two "Targe" from those for bargain off ebay. They are also so cheap, that I'll get some designs just to kitbash their arms and missile racks for conversions. This way one and the same Mech chassis will suit different gaming needs (like modern IFV chassis often come with different weapons for different battlefield roles). Once all the stuff (there are about 12 different items from around the world on their way to Germany at the moment) has arrived I will review them and show a comparison before painting them up.
