it seemed to flex less than my TC4 with molded graphite.
Like I said, my TC4 fine, but I'm looking at other little details about a chassis that make racing easier. I want the best overall shaft drive. The new Tf TC4? I guess, but then again it has some TC4 parts I want to get away from. I like the little details of the Pro 4 and it's continued R&D progress. Only thing I wish HPI would do is redesign the diff cases that you didn't need to remove the camber link braces and upper deck to remove the upper diff case. Connect the upper deck to the bottom diff case, that would make it lower and stiffer. My 2 cents. I do wish HPI would make a US carpet specific version though. How about it HPI?
