I currently own a Taigen with IR and I am looking at getting a second IR tank for some backyard battles. Looking at the Taigen site, they sell a number of Torro tanks that are also available in IR. Are these compatible with each other? I assumed that they would be since Taigen sells Torro tanks but with HL, Taigen, and Tamiya NOT being compatible with each other I just want to make sure that Taigen and Torro are before purchasing.
