Hello im in the U.S. and im looking buy prob like 4 maybe 5 tanks, to run with my dad and a few buddies. But Tamiya is out of price range. prob gonna buy a Tiger 1, king tiger, Panther, I wish there was a Panzer 4 with side skirts. prob 2 M1A1s. do any of the companies tanks able to run more than one at once? I'm not new to RC or Models just new to RC tanks. any help and advice is welcome or places to get or discounts thx.

Taigen is the one that still produces an IR system out of the box other than Tamiya. (Not compatible with Tamiya....)
You would likely look at Imex out of Florida
