If I did the above and also moved the battery back would there be any advantage/disadvantage over the brass c block. Would it achieve a similar ftont/rear balance but with weight more central?

Thanks.
Where is the brass C blocks? I have yet to see anyone selling any.

There is another issue on top shaft.

The inner diameter is not align with the shaft.

See the below Facebook link for the video

It simply means top shaft gear will wobble, causing metal rubbing noise

Roger. Does the tmg under servo weight need attaching to the chassis somehow or is the servo on top enough?

We currently run 17.5 on carpet with a slipper eliminator and plastic diff gears, 4 gear 100k. No issues.

I’d really like to try 2 gear, but I’m nervous I’ll strip the gears. Has anyone here run this configuration successfully? Or unsuccessfully?

Rivkin said on facebook "More rotation and more grip" Which I think basically comes from more weight transfer from the shorter length.

Considering how smooth the car is I can see that being a good change. And that kinda makes sense that both the carpet and dirt kits came with the same chassis.
