one way diff

[mr yellow]

I have just purchased a second hand yokomo DB that I was going to use for wood racing,It appears to have a one way diff fitted,the front wheels still rotate when the brakes are applied.I have no idea what this is suppose to do,but it it suitable for wood racing or should i use this car for carpet racing.Fifth scale racing is alot easier.

the one way is best on carpet bud but can be run on wood

[Malcolm Williams]

As Si says the oneway is best for carpet, personally I would get a normal ball diff for the front when running on wood to give you your 4 wheel braking that your used too.
Its personal preference anyway, you may find that you prefer oneway for carpet and balldiffs for wood or balldiffs for both.
Good luck anyway

That is how the Yokomo BD comes as far as I know so it has not been a change that has been made to the standard car. I don't notice much difference but my driving is rubbish anyway so I wouldn't be able to tell. I did find though on advice from Colin (http://www.smartracing.co.uk) the car drove better (for me) on wood with the read diff slackened off. As for carpet the standard car is brilliant

Yes the standard BD comes with a one-way front diff and a one way centre shaft also. The grainger kit comes with a spool and a solid centre shaft. I use a standard diff front and back racing outdoors and have used a front one-way on carpet however using any one way outdoors makes for interesting braking where the car just wants to swap ends. I don't find much advantage using the spool and if you have a knock it usually break other items on the drive train like the UJ's. The one way centre shaft can be made solid by knocking out one of the rollers and inserting it back the other way making them both lock to the shaft failing that you could purchase the Grainger main gear adapter BD-630 :p

Derek,

With regard to your comment above, After watching your car on Friday night, I think you would benefit from trying a Differential in the front of your car, as it was swapping ends very easily. I think you'd find that you'd get round a lot more easier (and enjoyably) if the car was more stable.

Thanks John. Colin was intending to get a diff for the front for me. He said from the start that I would be better with this but we are waitng on some of the parts. Would you say I would be better to swap the diff back to the one way for carpet?

[John Lindsay]

It's entirely up to yourself Derek, personally I run ball diff's front and rear all the time (with the exception of putting in a front spool, or, fixed axle on the odd occasion)

I find that again, the car is a wee bit unstable with the one way up front, no matter what surface you are racing on, as it takes away any braking power the front wheels should have with a diff.

Best thing to do is try it and see what you think, however, I suspect that you'll find the car easier to drive with the diff.

I was running a one-way last wood night and the car was all over the place. Fitted a spool (solid front axle) and it made a huge positive difference. A one-way has a similar effect but without the ability to brake (it effectively turns the brakes into a hand brake as it only works on the rear wheels, very hard to control on wood!)

Personally I hardly use the brakes on wood, if at all most nights
