New Xmods:Its all about the diffs and the TX

sg219 · Post by **sg219** » Tue Oct 04, 2005 10:52 pm

I can't believe that no one has mentioned if the diffs have been upgraded or if the controller has been upgraded.

The chassis can always be modded and improved on your own, but the diffs and the TX remain a weak link.

Xmods need a real working and quaility diff. Thats the weakest link in the drivechain. IMO.

You either gotta lock it with some kind of substance or make it permenant with glue.

Its barely adjustable with the screws provided.

This car needs quality gearing. Whether it comes from RS or GPM, having that would propel the Xmod to such a higher standard.

Has anything been done to the controller on the new Xmods? Maybe a memory so that you can have your trims set and stay that way.

It really sucks to have to reset your steering trims everytime you have to fold the cute little TX away. It's soooo cute.

Make a real TX with trims and dual rate that can be set and stay set without having to rip apart things and do it manually. Sometimes resulting in other problems or results that aren't what you were expecting.

I'd happily pay an extra $10-15 for these features.

Maybe a chassis set would be nice too. I have about 15 or so Xmod TX's.

If you collect Xmods and enjoy them, why would you need a TX for everyone, especially with the crystal set that's avalible?

Thanks for the link, but....

How dare you post a link to MRCC.

Fuck them, I won't even click on that shit.

CJ or BettyK, drop some Diff pics please. A little info too.

Whats different?

i got no pics (hassle ph2t) but the evo diff is worse. it's held together with a pin that presses into place and slowly comes apart.
we stripped it within a week as a result, the old school diffs never stripped for me.

more annoying is the fact that the pinion gears in the evo diff are a different size to the ones in an o.g. old diff.

i'm yet to see a front diff, can't comment on that.

Wow, I can't believe the second-generation x-mod didn't come up with a better diff solution. I'm sticking with the MR-02 platform.

Shit, if the diffs are like that, I'm sticking to a gen1.

thanks for the pic civics

this gives you a rough idea of how the pin sits in the diff. you insert it into the left side and the end presses into the right half of the diff. the left half of the diff rotates around this pin so a normal screw is out of the question as a replacement.
you need something with thread on the end that will be buried in the right half leaving the main shaft smooth so the left half rotates smoothly. (make sense?)

If you turn real fast (or if you drift) the diff begins to slip which will eventually lead to a stripped diff. The noise is sorta annoying when it slips

the diff does suck.. it kinda ruins the rest of the chassis- we can only hope that gpm comes to the rescue. untill then, you really may want to wait to buy one.

i think we should start sending emails to gpm urging them to start on making the diff- if gen 1 alloy parts are anything to go on, they dont really want to make gears. how bout we say we will boycott the other parts untill a diff is released

when the diff is installed-nothing holds it together but the pin?

no bushings, spacers, or ears on the chassis to keep the halves together against torque?

is it truly that poor a design?

can we loctite the tip of the shaft to the right side? a pain in the ass, but could THAT work for now? if i understand the drawing correctly that would allow the left gear to spin free on the pin.

What about a tiny cotter pin?(sp?)

Drill a tiny hole and bend a peice of green paper clip in there.

Here's one....

I sorta like the Loctite idea, but I think you would need some sort of threading for the locite to fill in and grab ahold of.

What about glueing the whole thing together?

I relly need one in my hands to guess at anymore possible solutions.

gnubee · Post by **gnubee** » Wed Oct 05, 2005 3:44 pm

loctite can work without threads. if needed we could also roughen the very end of the pin with a crosshatching- applied with a pliers or a vise.

not threads, but locktite will grab it.

Now is it possible to lock the diff, like pre-evo Xmods?

i like the loctite and cotter pin ideas

sure, it's still 2 halves with 3 little pinion gears inside. it's just that the evo diff incorporates the cups into the whole unit.

pretty much

i've only seen one with bushings, bearings might hold it together better but it's still all down to that pin
