Just remember, only Tamiya tank kits, with the tamiya Seperately purchased Ir kit are complete ready to go. henglong and taigen require the tank electronics to be gutted and an aftermarket system to be installed to be tamiya type IR compatible. As stated HL discontinued IR, but taigen stil markets theor brand of IR, which only works with Taigen.

converting one of these other tanks takes some paitence along with some money.
Evyerbody here is happy to help you. i have a couple BARC systems and am trying out an IBU2 as soon as it arrives in the mail. The IBU2 looks cool because its one board do all plug and play, just get a better speaker than stock hl.
