You had me until you said SCX10 II. With all of the new trucks coming out the SCX10 just feels stale to me - ancient design with a centered trans. Sure, it still works well, but there are too many other options out there and in the works.I'm baffled why you haven't. TRX-4 is getting rave reviews except for a couple to-be-expected issues (electronics mainly), but should no doubt run circles around this HPI. Better yet order an SCX2 kit and enjoy the trails!
