I was lucky to get one which was brand new from aero-mate. It took a while, but it was worth it. I have a Tamiya tiger 1 and it is also great to work on and build, but the fact that the aero-mate is all metal really sets it apart. I have been studying the manuals and all the other documents that aero-mate has for the tiger tank so that when I get read to build it, I will have a better understanding of how to put it all together. Any advice?? Thanks for the videos and responses...
