i've sadly watched him break these guys and its not on him and i have chassis that are 3-4yrs old and no issues. he has now since built up his cars with old chassis (that he also got off me or in trade) to see if that remedies the problem
my 4.1 is coming and i prolly will also tear it down and put it on an old plate til this is resolved.
the guy is good, not some club chuck tryin this lil buggy thing while not floggin a clumsy 8th scale. he's in the show every wk indoors and at outdoor track is in with a shout for the win each wk.
