Rear Roll Center

07/31/2014 at 1:02 pm

In my opinion, understanding roll center and using it for tuning is very important. It’s also one of the fundamentals of H2 Riku suspension.

For those of you that mess around with actual cars, the general rule of thumb is to keep the roll center close to the car’s center of weight to reduce roll. Hence the reason why we like to keep suspension links parallel with the ground. But because RCs are so light and use low grip tires this usually isn’t the case. Here’s what my rear end looks like. This is before I threw in adjustable rear hubs so my roll center is a little bit lower currently compared to this picture.

The DIB runs fairly well out of the box but I’ve already made the following changes to it:

  • 1.5 solid rear axle
  • RC-ART 13t front center pulley
  • Vertex Yellow front and Blue rear progressive springs
  • Rear mounted shorty lipo (SMC 4300mha)

Always worth the 1 hour + drive.

Sold the R31-RWD + DRB

Decided to sell the R31-RWD. Reason being I received my DIB v2 shortly after I got the R31 and would rather stick to CS right now. I’m also fairly new to RC drifting so I want to be able to properly drive a CS car as well. I gave/traded the DRB to a friend as well, didn’t feel the need to have two cars.
