I doubt they are defect, they are race bred, quality alu the loads being applied by modern motors and the lightweight race precision of the 7075 Al, something will ultimately lead to failures somewhere without a clutch.
TBH, we celebrated his first breakage as up until that point we couldnt get that much power to the ground with our chassis setup. (as we used 6.5T previously, now down to 4.5) It may be aging wheelhubs too..
Regardless, it's just a matter for Luke to better control his throttle off the bottom rpm range or use the steels and sacrifice some weight.
