That's a nice one. Looks just like the 2.4ghz you get when you buy the redcat 8th scale e-buggy or 4x4 short course vehicle. Not for nothing but once you add the crazy $30 shipping that seems to be the norm (for me anyway) from hobbycity you can probably pick up one from a domestic dealer and probably cheaper with a little shopping around by part number.
