A plastic spur gear acts like a torque converter. You’ll never see it with your naked eye, but that tiny amount of flex that a plastic gear gives, really does some saving on other drivetrain parts. But I can see why he says what he says. And we both know for some reason all arrma vehicles with plastic spurs have issues. If that’s all u experience, it’ll leave a sour taste in your mouth for all plastic spurs.I know this is geared towards the k8s, but I've been running the same plastic spur in my ERBEv2 on 6S (same motor/esc as my outcast 6S, max6/blx2050kv) with similar top speeds. For about a year. I need to weigh the two trucks... the ERBEv2 may be a bit lighter, but I was even running the same 3.8" trenchers on it. Oddly, it's diffs have held up better than my outcast, which I switched it's tires to the stock backflips.
