  • I just finished running my BD across the setup board; all I can say the car is very well balanced. I've never gotten a touring car perfectly tweeked without a lot of adjustments. The BD came off the tweak station pefect without adjustment. I haven't gotten to drive the car on the track yet but with all of the weight moved forward (batteries, motor, servo) it should steer awesome. Yokomo has built a winner.
  • Glad to hear that, I'll be getting one soon...I hope - JB
  • I heard there were two BDs running in the UK today ordered from japan... anybody on here???? any shops sent to the UK?

    The source that told me is usually full of bull excrete though.

    Oh yea Get that heavy grease out of those bearings...Man once i did that the drive train was free as a bird MAN...lol
    With the big pulleys and adjustable tensioners in the bulkheads, I wasn't planning on running the tensioner on the upper deck, is there any reason to?
  • Not really, other than to take out some of the belts "backlash" or bouncing around during stop and go... stop and go.

    On the rear diff, I found it a tad tight with the shim on each side. So I took out the shim on the long side of the diff (left side).

    I would run it if only to save on wear. The antenna mount is real close to the belt and any slap could begin to rub a little. I found that the tentioner is really just to keep it from the STOP AND GO back lash. I didn't have any problems with it so I will leave it....But you have a good point. with all those diff adjustments why would you need it? Hey I am new to the adjusting diff what will each tick mark do? going tighter front or looser and vise versa?
    Just trying to get a head start on tuning knowledge...This is my first real belt car...I do have a Yokomo Mini TC but it is basic when it comes to belt cars. LOL I am going to sell it soon as I never run it and I don;t have time to keep it maintanced...If Anyone is interested send me a PM.
    Thanks,

  • lol, i never thought about belt tension etc... going to be strange running belt again.....
  • Does anybody know why the pulleys aren't made out of aluminum as shown on the yokomo website pictures of the BD
  • I guess because that was a prototype....

    Might be worth an investment though.
  • maybe too expensive to replace if they warped or somehow got something caught in it and broke a tooth? - JB
  • FW-05RR--- my guess would be one of Two reason they are plastic, cost and or less rotating Mass
