Differential Cup trick to lessen damages | ZD Racing 1/8 RC

The solution to cavitation of the center differential outdrive flat-shaped cups has been just around the corner all along..
The answer is the round shaped outdrive cups of the front and rear differentials..
The round ones are more durable than the flat ones.
I hope this trick helps everyone.

These parts are wearable parts like tires, whatever brand you have, you will have to change it from time to time. I suggest you inverse your cups when a side have too much wear so it will double the part life. You can also put dry PTFE to help but the cost should be very low to change, lower than changing tires.

Thank you. Yea I agree. I used to always invert the same parts. But the material used in these cheap gears are just not as good as the high end ones like Traxxas, tekno etc. So, they wear out twice faster.

@@ianbudgetrc2574 Now I read you I am thinking about buying a lathe machine to make my own part :-) It would cost more than a Kraton but would be more fun..
