The cvd snapped part way along the shaft, so I doubt thats a workmanship issue more a faulty part. Having read the manual it is rather poor at describing how to build the car rear motor though you would hope to notice it was the wrong way round!
Others were a front upright and a rear wishbone and neither driver had spares (and nobody else had an H2 at all so that ended the day).

Its not statistically large enough as a sample to say either way but all I'm saying is that suggesting the H2 is more robust has little supporting evidence either.
