    Drivetrain slop

    So my truck is down for repairs
    Saw this idea a while back just never tried it, untill now. Had a extra gear laying around figured give it a try if it works I will do something a bit better
    But from my first look and feel seems it should work.just did low gear slop isn't
    A big issue in high gear,for me anyways

    What did you do?
    Whatever it is I just said... I could be wrong.

    Ive seen the other thread about this and it looked like a great idea... but like jimmie said, Its hard to know what you did without an explanation or other pics. I remember a bit from that other thread but not enough to spot the differences.

    Thanks, Jamann.

    From what I think I might see, it is stronger than the other mod I have seen to these gears to remove the play.

    Well I have run it a few times (not with brushless) working fine.a definite improvement just better control and the roll back is reduced quite a bit.
    It doesn't get the chance to build up momentum before it catches. So the roll back is much more predictable and controllable. It's not a worm geared axle by any means but much better.
    On a side note the hub mod is also working quite well

    I like this way a lot better then the other sloppy fixes. This way can be reversed if needed. The other ones involved cutting and shaving that is not reversible unless a person buys a new gear set. I will be trying this. Thanks jamann

    Lol. Don't feel bad. Traxxas has had my rx and tx and motor sense the 11th. The sad part is I still haven't herd from them yet. Grr.

    Mine is glued in its there for good
    The gears are cheap at least.i looked at the other one and decided to try this one for two reasons.
    1) no real shaving or cutting the gear at all.Easier I like the kiss method of things
    2) The other way it only engages 180 degrees apart so in two spots this way it's every 45 Degrees in 4spots
    I am quite happy as either way you do it it helps for climbing.
    Oh how the mighty have fallen.....

    Next time you do it make a plastic mold of it (plastic mold kits sell for $20) at hobby lobby and viola, instant all plastic no slop gear. Just as indestructible as the plastic original. And a lot of summit owners lining up to buy a high and low set ($18 shipped).

    Second idea. If you don't want to go into business than skip the styrene and fill the whole with J B weld. You can shape the two part epoxy before it dries and it will be as strong if not stronger than the original gear.

    that was my next thought jb weld...i like how you think. more permanent.i like the slop removed in low gear just makes it a little more controllable.

    For what it's worth, I should mention that if you add jb weld or anything similar, you should try your best to make it 180 even as to keep the gear balanced. You don't want one side heavier than the other, or it'll be very bad on gear mesh and every thing else. =)

    To anyone who's done this, how much harder is it to shift gears?

    When done correctly it shifts normally
    No difference except the majority of the slop is removed.

    does the truck need to "roll" a little further before the gears actually mesh during shifts?

    I haven't found plastic that will stand up to the forces being applied to it yet.
    LEM is said to be working on one
