Default Ball differentials...need two sets?

Hi,

So despite the warning, I have put some SLIGHTLY larger than normal off road wheels on my dusted off TA03F for running around the garden.

On a whim, I also bought a 'ball differential set' (part 53267) off eBay as it seemed cheap enough at $25. I'm now wondering if I should have bought two sets because clearly it's just for one gearbox. Nothing seems to suggest buying two - is that just meant to be common sense or is there a reason you only use a ball diff in the front or rear? I presume the benefit here is just like any ball bearings to make things run a little smoother and not for any change in driving characteristics.

Use the diff for the rear and you can always upgrade the front later.

Overall, the ball diffs allow for much smoother running/handling. The bevel gears are acceptable even though they tend to wear down and loosen over time. You do have the option of adjusting the remaining diff gear by packing it with either a lighter or heavier grease.

Thanks! I enjoyed making the chassis. The TA-02 was preceded by the TA-01. The TA-01 chassis is still used in the Hummer. Don

i thought about it since i have 3 of them sitting on the shelf. gearing a 17.5 or 21.5 would be rough. you'd have to run a co27 to stand a chance i think.

I'm still thinking about it. You've got to have the speed tuned gear set and use the 66T. Get the 28 & 29 pinions from HPI (E-10-.6 module) and you have 5.75-5.55 gearing. The rest is just bolting on wheels,tires and mounting a TA body of your choice. Don

Pic of an update I made to my TA03 using an old TC5 P-DUB bumper. Not pretty, yet, but more functional than the optional Tamiya foam bumper. The glue is between the foam and a strip of double-sided tape that holds it to the base plastic bumper (same as the option foam.) Only needed the glue to fill the gaps that I left when I did the hack job. A cleaner cut will eliminate the need for it. The P-DUB bumper is stiff, and wide enough to protect the wheels/front suspension. Would have been better if I'd spent more time in cutting it to fit the contours too, but not bad for a first swag. It currently fits a Tamiya NSX body just right.

I haven't yet but if it doesn't get rained out again I should be soon... not sure if it will be better than the 2 diffs I run now


Has anyone come up with any practical ways of keeping the motor cool in a TA03F... I am expecting to be racing in 30+C the next few meetings and I think cooling could be a premium... I am running a 10.5
