    The nuts in that kit are all you need.
    Do the 17 mm hub mod and done.
    I did it a while ago not a issue anymore

    Alright, Im guessing I have to buy the whole kit to get the nuts or can I buy the 4 nuts separately from somewhere else?

    Here ya go. All you need is a hack saw and a vice of some sort. Then use those nuts and your slop problems are gone.

    FWIW, the 17mm hubs I used were VERY worn out and had TONS of slop. After the mod there was zero slop.

    Hub Slop Elimination

    I much prefer an elegant insertion of a stainless steel helicoil to hacking up a part that is 99 & 44/100 good. It takes a bit more work, but you are left with an essentially unchanged Traxxas part.

    Can you elaborate on the Stainless steel heilicoil. did you insert it or did you buy it that way.

    I think first I'd like to say that there is definitely a place for pav's method. It is cheap, effective, and relatively easy. There is NOTHING wrong with it, but we're all allowed to have our preferences.
    I made the one in the video and a few others like it. The hubs were wobbly enough that the axle threads had cut into the outer part of the axle hole, even though they are not supposed to touch.
    I used a drill press and a home-made jig to drill the center holes to 13/64", which is the correct size for installing M5 helicoils or permacoils (same thing.) The drilling takes off a very small amount of aluminum. You then need an M5 helicoil/permacoil tap to cut threads in the aluminum hub. I did this by hand. You then need the M5 coil installation tool to screw in the stainless steel coil (I used a 7.5mm length) and a small punch to knock off the coil's tang. Screw the hub with coil onto the axle and insert the stock grub pin because now you're done.
    Now here's a BIG "However":
    It is possible but not likely that the grub hole in the hub will not line up well enough with the hole in the axle for the pin to go through. There is no control for this with the limited tooling I possess. I will say this though: if a hub will not work on a particular axle, in my experience it will always work on one of the other three.
    There you go: more than you wanted or needed to know.

    WOW you really put some thought and effort into it. It looks like a great solution. I wish Traxxas could see what you did and have some hubs made as an upgrade. Wishful thinking I guess. Thanks for the detailed info.

    Haha... KSB... were no longer friends because you have different ideas than me. Consider it over.

    I do agree fully, lots of ideas only gives us more choices when it comes time to fix/modify/improve. Im lazy, so the hacksaw and hpi nuts was my method of choice. But its not as "custom" as what KSB is doing.
