    Default UberRC HD Ball Drive System - Install & Review.

    Hello,

    Hello,
    Was excited to recieve the new UberRC HD Ball Drive System in the post & couldn't wait to get them installed. First thing you notice when opening up the packet is the quality of the finish , attention to detail & overall solid look . I couldn't help dry fit it all together & noticed the zero rotational slop between all the components.






    Here's a comparison photo between . HPI @ 4mm , My own custom cross overs @ 8mm & UberRC new Ball Drive System @ 9mm.






    Prep The Boots

    Cutting the first bellow off the Boot will leave you with , roughly 9mm dia hole .( My prefered boots are the stockers because there more flexible than most & less likely to distort )







    Once trimmed the boots will stretch over the end of the bones dry.



    Grease Them Up

    UberRC highly recommend the system be run fully booted & greased.

    A few brands of multipurpose grease all of which would be up to the job. (Lithium Moly)



    I began with the BB housing filling them completely



    I've used FG ball drives in the past .the Uber BBs are bigger @ 6mm + there's 5 not 3 per cup





    This is a good opportunity to service , rebuild or upgrade your Differential at this stage. Mine was all good ( i only run a 26cc motor)
    The Differential gear pins are captured using grub screws instead of a bolt. ( This only needs to be nipped up)




    Repacked the diff with the remaining grease & rebuilt the gear box . Then fitted into the the car.




    This is the first UberRc product i have fitted to my BAJA besides bearings. Properly maintained i really can see it lasting. I'll post back my findings regarding durability etc.
    Run a few tanks today and the car feels more stable in the corners ( It runs very Smooth )
    Thanks for looking hope it was helpful.

    Edit: Only 12 photo's per post .i'll tag on the missing shots.

    That's true , Look along the leading edge of my lower arm . I've made Boot protectors using old FG tyres . Never split a boot since i fitted them 2 years ago. And they keep the drive line clear of debris.

    Nice fitting review John.

    The cups are case hardened which gives this finish, it can be polished back to a shine, I'll get pics of my set up soon.

    am i right in thinking you dont need toobz for this set up??

    Also..

    was it hard getting the ball bearings into the ends???
    if its got tits or gears its going to be expensive

    Toobz wont fit for sure
    Not only that, but even if they would fit, totally unnecessary.
    Bearings can be pressed in by hand/thumb. Only one of them in my case was a bit difficult and needed to be convinced to go in with a needle nose plyer.

    If you have ordered the ball drives ? start stripping now. The write up slowed me down , but i'd guess you could swap it all out in 40 mins.

    Found this.

    With the ball drives system, what is the degree of angles drop n still maintain smooth articulation?
