The universal driveshafts should be a bit smoother, or just replace the worn drivetrain parts.
The car is brand new. Put it way last year after this all started up. Heres someone elses quote from rc car actions forum
I'm running a Tamiya Mini M03-L.
It appears that when I throttle the car and turn at the same I appear to get a rather loud grinding sound coming from the car. This sound does not come when running straight. When this happens the car's performance drops, and so doe's the speed.
I was told by some other members to Install the Tamiya Universal set which I have done, and I'm still experiencing this grinding noise when the car is turning.
The noise comes from the Gear shaft, and it happens whenever turning and throttling...
Can anyone offer me so other advice?
My parts are all pristine looking to. Ive tried a boatload of o-ring setups with no luck. This problem is heard of here and there with now fix. Can you give me your full front end setup, including orings and whatnot. Deffinatley not and gears griding though.
