Kapitan

Hi, Im interested in purchasing a Tamiya f104 but unsure exactly which model to get. I've looked at the Tamiya f104 black special which looks very nice but since the f104x1 is on the horizon im not sure whether to wait for the new one or get the current model. So my main question is how big is the difference and should i wait or just go ahead and get the black special? Or are there are any other competitive models I should know about?

Also any recommendations for good electric components for these cars. I already have a radio & receiver. I will be running Lipo batteries.

Thank You!
