The WK is a waste of money IMO. I had one and it just took so much work all the time that in the long run I should have just bought a real truck..
Now I have a SCX10 that I'm building a toyota scale truck. Not done yet but I'm doing cab and all from styrene myself and it's my first time working with it. The truck can handle what you do to it if you choose the right set up and equipment for it.
Or you can get the SCX10 TR RTR and upgrade as you go to the electronics you want..
