This new package by Street Jam looks to be in direct competition with the recently released MST MS-01D Pro chassis. The original OTA-R31 chassis was a very well designed chassis. One of the first to introduce the in-line longitudinal battery position, which is now evident in Yokomo’s new DIB chassis.

  1. This doesn’t mention the ackerman fix they did on the R31X. I wonder if you still have to do the TA05 Diff mod on the steering knuckles.

        I found this by googling banggotan and then later found another build from him about the R3X found here. http://csjunkies.com/viewtopic.php?f=7&t=1248  The very last post mentions that the steering cranks were moved back a bit to fix the ackerman.
