The vehicle designs that you build seem unique to this brand, and not to LEGO. The core communication components of the receiver/controllers are also like nothing I've seen. I was mostly wanting to share it with others because I think it's very interesting, but didn't want to break the guidelines or anything. Anyways... posting the below youtube video I made that simply shows how the device mechanically works. Not any vehicle. Just how the hardware works. I could not find answers to my questions online for these things, so I purchased 2 of the tanks and their humvee so I could test it myself. My findings were satisfactory. Figure people who like to build lego technic based RC vehicles with relatively simple controls would love this tech.The power function stuff is more complicated and requires switching channels to manage the mechanics. This is more streamlined.
