  1. Hey I heard that the gears in a Yokomo MR4TC may be used in my associated TC3 gear box with little to no modifications. Is this true? and if so where can I get these gears and which part numbers do you suggest?

    • Not 100% sure, we have never had any experience with it.  It might be likely, there was a time where Yokomo and Team Associated TC cars shared very similar designs.  Again, not 100% sure, you would have to be a guinea pig to test those gears….

  2. just brought yokomo 2.0 and it is a plastic diff.  you think it would be metal for the price (poor effort Yokomo)

  3. hi, im new to RC drifting, is the yokomo 2.0 FCD solid axle all i need to countersteer ? or do i need the gears too? or does it come together already? thanks.

    • Of course you can. For example in our MR4TC SD, we use Yokomo 1.5FCD with Kazama 40/10 (Stage 1 CS) combo for a total of 2.54 CS ratio…. just noticed that the kazama CS gears are not listed here… those will be added soon 🙂
