Default Diff loosening problems

Guys;

While my diff was disassembled to add loctite to the adjusting screw, I thought of something.

The short side from the Pro-3 diffs will fit if you cut/grind down the center bearing support to match.

This would allow you to build the thrust bearing in a more conventional manner with the spring in the outdrive opposite from the bearing.
The screw head would also now be on the opposite side outdrive (from the kit) and I'm not sure if this would lead to other problems.

Has anyone tried something like this and what success (if any) did you have?

Thanks,
Steven

Default Thrust bearing

Can you use a regular thrust bearing instead of using the thrust balls and plates for the diff?

how long did it take for your orders to arrive? USPS global airmail was the method of delivery and so far after a week no sign of it.

All this talk about breaking stuff makes me really appreciate the outdoor tracks here in England - grass runoff areas!

1. new 1.1 version gears
2. HPI Backing plate (if your going to use the oneway)
3. extra arms etc....

You should already be pretty well set-up....
O.K. will do. Thanks

Pops,

By having the screw head and thrust bearing opposite to the spring and nut, you get the old version of the stealth differential. I know this works MUCH better than how the diff is currently built. I find it funny how I get NO response from HPI in regards to the Diff design. I think this like my fourth or fifth post on the subject; I wonder when they'll get around to answering my question.....

I tried various parts/configurations/combinations with little success. Perhaps you can spend more time trying parts that i didn't....

I think I'll send PRP an email describing the problem, and hopefully, they'll make a solution to it....Seems like HPI isn't....

They should make the hub bushings chrome, get lost on the track easily if you lose a knuckle.

Where I come from, ppl have been losing that often. I've lost one myself too...

Do what we used to do with our 1/8th scale front dogbones. Paint the bright orange.

Default "Custom" Pro-4 diff building

RCBuddha;

I am going to see how well the Loctite works. If the results are not satisfactory to me, then I am going to build a Franken-diff using parts from both Cars.

Thanks for your input,
Steven
