    Hey guys, I race with Mimno and his problem seems to be drivetrain related, so any idea's on what may be causing it would be most helpful.
    His motor's and electronics are going fine in his MR4TC and he knows how to gear properly, when on the track it just seems like he's running a stock motor when everyone else is running a mod.
    The car doesn't pull to one side so it doesn't seem related to one particular side or corner of the drive train, he's tried various belt tensions, at the moment it's just slack enough to make the usual XXX-S belt slipping sound under hard braking. His diffs seemed slightly tight when I fealt them but not hugely so, not enough to slow him down so much anyway.
    There isn't any excess noise from his car on the track, so gear mesh seems fine, could a badly moulded spur gear still cause problems?

    He's rebuilt the car atleast once so I would of thought he would notice any obvious problem, he's an engineer so knows how to build stuff too I hope

    check to see if the spur is rubbing up against the tensioner,i had this problem and talked to todd hodge,he found it and had me put a shim in between the two.

    I think you might want to try to remove the motor first, and then try to push the car on a flat surface. It should be very free. If it's not free...there might be somethin wrong in the drivetrain.

    I suspect it might be a faulty bearing. Another thing is that you might also want to check the spur gear assembly.....the shaft holding the spur gear might be too short. So that when it is installed in the chassis, the spur gear does not rotate freely.

    Great! you might want to use some thread lock on the screws such that the screws that secure the top shaft wouldn't come lost.
    Or you could just use one long screw with a mini lock nut on the other side....it seems to hold everything better then the two screws. I always had one of the screws loosen up on me after I did this I never had that happen again. Just be carefull not to tighten the nut or the screw too much and pinch the gear between the chassis sides.
  • gear alinment
    Kenin K.--That sounds like a very good idea.
    Simple fix for a simple problem,I have not had the gear
    problem-but have seen the screws back off.
    I might try it on my xxx4 @ this week end s off road race,


    Thanks for the idea!

    What is the trackwidth when using tc3 hexes? We run rubbers and following the setup on the manual (inner holes on the rear arms), i get a width of 186mm. Hope it is closer to 190mm and not over. Thanks in advance.

    It should be pretty close to 190. I haven't measured it but my car has never failed tech inspection with the AE hex's on.
  • I think they are exactly 2mm wider than the stock Losi ones, bringing it up to 190mm.
  • STLNLST, LouisB
    Thanks, i'l give them a try. Also, are there aluminum hexes like the yoke (pin and o-ring type) that would fit the losi?
  • Yokomo has those types....I think that they are called E-Z hubs. It's up to you which one's you want. I like the clamping (non O-ring) stlye hubs myself.
  • glide 1: i used to have one of those in my losi. their made by dynamite
  • Clamp type hexes
    Thanks STLNLST, Koya

    i have those now, the red ones made by dynamite, will those make my car wider, like using the TC3 hex?
