RE: confused
I see that you ordered from rcdynasty, they are Mato's ebay site, which is a good thing, Mato is a good company. The tanks you linked are the IR versions and as Airbrushler stated you should be getting everything you need to battle these two, in my opinion I believe you will be fine. Hope this eases your concern. If for some reason you would not receive the items for battling, send them an email or call and they will make it right. But like I said I don't for see a problem.
Cheers,
Wade
