I'm looking at getting some 1/24 (IR) VsTanks for my sons and I but I have a few questions about them.

1. I'm not looking for anything super fancy for us, but are these tanks of a fairly decent quality? I have 5. for example my m1a1 vs t-72 and a late tiger vs sherman. I love them both.

2. Do I need to buy different model tanks to have them fight each other with the infrared (i.e. only one M1A1, one T72, etc)? sound like a good idea
