I'm wondering if someone can help me here. I purchased a pair of Blackfoot 2016s and am totally stumped by a significant drive-line issue. I have gone over the assembly a number of times and I cannot understand why the right side (motor side) CV easily pops out of the cup. I can easily pull it out with my hand when the entire unit is assembled. It's almost as if the joint are a few millimeters too short. Have I assembled it wrong? Is this a flaw in the design? I ran it all of one minute and, sure enough, the CV pops out of the cup. I'm almost regretting I bought 2 of these! I have attached a couple of pics. Here's hoping someone has a fix or suggestions. It seems odd that Tamiya would release this truck with such an obvious flaw, given the Monster Beetle's release last year.
