    pinion question

    Just bought 2 new Xmaxx's for my Boys,
    already searched, didn't see this as a suggestion anywhere.

    having same issue in each of them,
    pinion's keep slipping out, grub is tightend and loctited, aligned with flat spot. (stock gearing)

    wonder if something like this part would work better

    as the center bore is shaped for the D Shaft., haven't been able to find the same kind of part made by Traxxas or anyone else. anyone try this?

    Pinions coming loose - common issue
    Red loctite - maybe a few times have worked here

    The ara number would work

    thanks.
    Gonna run out and grab a pair of them.

    one of the things I noticed about the 2 xmaxx's we received, must be a refresh,
    as both of them included the traxxass body reinforcements already installed. only reason I even noticed is I already purchased the proline version prior to arrival with intent to install, now I have 2 extra sets

    Mine comes with body savers from stock too.

    someone else had this idea and already identified an issue with this



    seems like the flat side on the motor isnt deep enough

    may have to shave a little bit further back on the shaft with some dremel work, good find, thanks!
